1.4 GENERAL DESCRIPTION

The EVM provides a tool for generating, eXeCU1:1ng, am debugging MCU code. By providing all of the essential timing and I/O circuitry, the EVM simplifies user evaluation of the MCU ..

Operation of an MC1468705 MCU is simulated by the resident MC146805G2 MCU. Data transfer within the EVM is controlled by the monitor RCM firmware. In turn, this ROM is controlled from an RS-232C compatible user-supplied terminal. User object code may be generated using the resident one-line assembler/ disassembler, or may be downloaded to the user program RAM through the host port or cassette port. User object code may then be executed using various debug commands in the monitor. Code may also be executed from reset using the USER RESET switch. MCU EPRa1 is simulated by write-protecting user program RAM during program execution.

Simulated MCU parallel I/O ports are available for external connection. These lines are also used to control the MC1468705 on-chip EPRCM prograrrmer. The EPROM is programned am verified by inserting the MC1468705 device into the correct socket and entering a monitor comnand. The object code in the user program RAM is programned into the MCU EPRG1.

Prograrrming is different for each MCU. The monitor firrrware PR<M must be changed by the user, depending on which MOJ is to be programned. A jumper select option allows either the on-board clock or a user-supplied external clock to be used. A printer port is provided which is Centronics-compatible. User circuitry may be added on the wire-wrap area of the module.

Optional kits of firrrware and software are available for operation of the EVM wi th an EXORset host. The Motorola part numbers for the kits are M68EVMSETG2 aoo M68EVMSETF2.

2.4.4 Printer Installation

".rne ErVM is designw to drive any Centronics interface printer. wnen purcnasea from Motorola, the printer is supplied with a cable. The cable may be purchased from Motorola by ordering part number MEX68PIC.

The user may manufacture this cable, although it is a more complex assembly than ribbon cable and connectors. Figure 2-15 shows the interconnection diagram of the cable and lists suitable connector part numbers. The cable may be keyed on the edge connector to prevent incorrect cable connection.

The cable is connectoo between the EVM ooge connector J9 (PRINTER) and the user printer. Be sure to orient pin 1 of the cable with pin 1 of J9.

2.4.5 Audio Cassette Player Installation

An audio cassette player may be used to save program object code from the EVM. Two signal lines plus ground must be connectoo to the cassette player from EVM J6 (EAR) and J7 (MIC). An inexpensive cassette player, GE model 3-5153, may be used.

The user must buy or make a cable sui table for the cassette player used. An audio patch cord (Radio Shack part number 42-2420) and an adapter (Radio Shack part number 274-327) may be used with most recorders which use miniature phone plugs.

The cassette player is connected to the EVM by connecting the adapter to EVM J6 or J7 and the pa tch cord between the adapter and the cassette player. The data out signal at EVM J7 (MIC) should be connected to the MICROPHONE input of the cassette recorder for saving programs. The data in signal at EVM J6 (EAR) should be connected to the EARPHONE output of the cassette player for loading programs into the EVM memory. ~ound connections are part of the patch cords.

CHAPTER 3

OPERATING INSTRUCTIONS

3.1 INTRODUCTI ClJ

This chapter describes the operating procedures, MCU EPROM programming procedures, and the debug/monitor commands for the EVM.

3.2 SWITCHES AND INDICATORS

The EVM is provided with five switches and four LED indicators. The indicators show the status of certain functions during EPROM programming, and may prompt the user to perform some function. See Figure 2-1 for location of switches and indicators.

3.2.1 Switches

Two switches (Sl, S2) control the user reset and abort functions of the module. Two switches (S3, S4) control the EPROM programming operation, together with the LED status indicators. A master reset switch (S5) is also provided.

USER RESET - The USER RESET pushbutton switch (Sl) , located on the upper left corner of the EVM, is used to reset the MPU and all user I/O, and swi tch to the user map. The USER RESET swi tch may be used as a permanent map switch for execution of user code from the user reset vector (see user map description) •

ABORT - '!he ABORT pushbutton switch (S2) , located on the upper left corner of the EVM, is used to return to the monitor map from the user map (see user map description). The ABORT switch has no effect when operating in the monitor map.

PROGRAM - The PROGRAM slide switch (S3) , located on the lower right corner of the EVM, is used to activate +12 Vdc and +27 Vdc power used to program the EPROM. LED indicator (CR7) is lit when this switch is in the ON position.

+5VOLT - The +5VOLT slide switch (S4) , located on the lower right corner of the EVM, is used to activate +5 Vdc power used during the programming and read operations. LED indicator (CRa) is Ii t when this switch is in the ON position.

MASTER RESET - The MASTER RESET switch (S5) , located on the lower left of the EVM, is used to perform a power on reset of the entire EVM.

3-1

3.2.2 Indicators

Four LED indicators show the status of the programmer circuitry.

PROG Red LED indicator (081), when lit, informs the user that the device in socket XU56 or XU57 is being programmed.

VERF Red LED indicator (082), when lit, informs the user that the device in socket XU56 or XU57 has been programmed and verified.

PROGRAM - Red LED indicator (083), when lit, informs the user that PROGRAM switch (83) is in the ON position, applying -12 Vdc and -18 Vdc to the device to be programmed.

+5VOLT - Red LED indicator (D84) , when lit, informs the user that +5VOLT switch (84) is in the ON position, applying +5 Vdc to the device to be programmed or read.

3.3 MEMORY MAP CONCEPT

The EVM is designed to operate in either one of two maps (monitor map or user map). The monitor map contains 4K bytes of RAM/ROM which includes the monitor ROM, monitor RAM/stack, monitor I/O, a monitor control register, and a user stack pointer (see Figure 3-1). The user map, which simulates the MC1468705 memory map, contains the user I/O ports, user RAM/stack, and user pseudo RCJv1 (see Figure 3-1).

The memory maps are decoded with a field programmable gate array.

NOTE

The entire 4K-byte memory map is available to the user, although all MC1468705 MCU devices do not have EPROM throughout the entire 4K-byte map. Refer to the specific device data sheet for valid program locations.

3.3.1 Monitor Map

The terminal, host, cassette, and printer ports are available only in the monitor map. User programs in the user map can not access the peripheral ports.

3.3.2 User Map

All user I/O ports lfi, S, C, D) are available in b~e user map for evaluation. All ports are reconstructed off chip except port C.

User pseudo ROM - The user progrc?-m space (080-FFF) is RAM, which is write protected during user program execution. This feature requires all programs to be ROMable and protects against program errors which would otherwise overwrite the program space.

Header J8 on the EVM provides a simulated 8K user map for evaluating the MC146870SG2, and a simulated 2K user map for evaluating the t-K!1468705F2. Although the EVM has only a 4K map, the user vectors fetched from IFF6-lFFF or 7F6-7FF for the MC146870SG2 arrl MC146870SF2, respectively, appear to the ~I.M MCU at lFF6-lFFF. This is accomplished by shadowing the lower 4K map into the upper 4K map (8K option), or by multiple shadowing the lower 2K map into the upper 6K map (2K options).

WRITE-PROTECTED DURING USER PROGRAM EXECUTION

3.4 MAP SWITCHES

IVN types of map switches are provided -- a ternfAjrary' swi ten which allows modification of user memory under monitor control, .and a permanent switch which allows execution of user programs&

3.4.1 Program Execution

A permanent map switch for execution of user code can be initiated in two ways:

Command from the monitor

The monitor commands G (execute from address), P (proceed from breakpoint), and T (trace instructions) allow execution of user programs.

Pressing the USER RESET switch (Sl)

When the USER RESET switch is pressed, the MCU and all user I/O are reset, maps are immediately switched to the user map, and the reset vector is fetched from the user map by the MCU. Breakpoints are ignored during this mode of execution. Execution can be halted only with the ABORT switch.

Return to monitor control occurs in two ways:

A breakpoint or the end of a trace function in the monitor

Execution of user code continues until a breakpoint (SWl) is encountered or the ABORT switch is pressed. The map is switched back to the monitor map after the registers are saved on the user stack. An SWI which occurs when no breakpoint is set -- and when the ABORT switch is not being pressed -- does not cause a map switch. This allows user SWI's to be executed in real time.

pressing the ABORT switch (S2)

The ABORT switch, when pressed, forces an SWI on the data bus until the next LIR. The registers are saved on the user stack and maps switched to the monitor. The ABORT switch has no effect on the monitor map.

3.5 LIMITATI(l.JS

No protection is provided to limit programs to the exact aIOOunt of EPROM avai lable. '!he user must be aware of ~'1e map of the MCU being evaluated and ensure that only valid EPROM locations are used.

AI though an external clock input may be used to evaluate the MCU at reduced speeds, LOAD, TPLD, and TPDU functions may be used only while operating at full I-MHz rate. TO operate at reduced speed with an external clock, the following procedure should be performed.

a. Load the program (LOAD, TPLD, or TPDU commands) at full I-MHz clock rate.

b. Press and hold the MASTER RESET switch while positioning the jumper at J13 to pillS 1 and 2. ~~'hen the Jumper is in place, release the ~~tSTER RESET swi tch •

3-4

c. The user program can now be executed and debugged at reduced clock speed.

d. To return to full clock rate, repeat steps band c moving jumper on header J13 to pins 2 and 3.

'!he baud rates of the terminal and host are independent; however, during transparent 100 de , characters from the host computer to the terminal may occasionally be lost if the terminal baud rate is not higher than the host baud rate. This occurs only during the transparent mode, and does not apply when downloading to memory.

'!'he audio cassette format is unique to the EVM and is not compatible with any other tape format.

The printer port does not support any of the error detect lines. Only the data, strobe, and acknowledge lines are implemented.

3.6 OPERATIKl PROCEDURE

'!'he monitor is the resident firmware for the EVM, which provides a self­contained programming and operating environment. '!he monitor interacts with the user through predefined commands that are entered from a terminal. The commands fall into five general categories:

a. Commands which allow the user to display or modify memory.

b. Commands which allow the user to display or modify the various internal reg isters of the MCU.

c. Commands which allow the user to execute a program under various levels of control.

d. Commands which control access to the various input/output peripherals connected to the EVM.

e. Commands which program or read the MCU EPROM.

The monitor requires five bytes of user stack for user register storage on monitor (re) entry. No limitation is placed on the user as to other uses of the stack.

All user registers are in an unknown state on monitor power-up.

3.6.1 System Initialization

Turning power on initializes the EVM system. The MCU is reset and the monitor invoked. '!'he terminal displays:

EVMbug705 REV X.XX ?

s=xx c=XX A=XX X=XX P=XXXX

where X is a revision of the software or an unknown register state.

Other means can be used to reinitialize the EVM finnware (see paragraph 3.2.1) •

3-5

3.6.2 System Operation

initialization or the prompt ? and waits for a response. If an invalid response is entered, the terminal displays a "What?", and rings the bell.

A dollar sign ($) may precede any number input except bit number specifications in the BCLR/BSET and BRCLR/BRSET assembler mnemonics. All numbers are interpreted as hexadecimal -- the ($) is not required.

The user can call any of the commands supported by the monitor. A standard input routine controls the system while the user types a line of input. Command processing begins only after the line has been terminated by a carriage return (see note 6, paragraph 3.6.3). .

3.6.3 Command Line Format

The command line format is:

? [NO]<command> [<parameters>]

where:

? Is the prompt from the EVM monitor.

NO Is ~~e negative (opposite) of some primitive co~mands.

commaoo Is the primitive command.

parameters Are separated by a single space.

NOTES

1. The command line format is defined using special characters which have the following syntactical meanings:

< > Enclose a syntactical variable.

Enclose optional fields.

] ••• Enclose optional fields which may be repeated.

These characters are not entered by ~~e user, but are for definition only.

2. Fields are separated by a single space.

3. A maximum of 30 characters may be entered on a command line. After the 30th character is entered, the monitor automatically terminates the line and begins processing ~~e 3D-character line.

... ,. "-0

4. RETURN (CR) (carriage return) enters the command line and causes processing to begin.

5. CTRLrX cancels the entire input line.

6. Parameters are interpreted to be the last two or three characters in the parameter field. Parameter errors may be corrected by re-entering the parameter without a space.

3.6.4 primitive Oommands

Monitor primitive commands are listed in Table 3-1.

Each of the individual commands is described in the following paragraphs.

3-7

3.6.5 Assembler/Disassembler (Interactive) ASM

ASM <address>

where <address> is the starting address for the assembler operation.

'!he assembler/disassembler is an interactive assembler/editor in which the source program is not saved. Each source line is translated into the proper machine language code and is stored in memory on a line-by-line basis at the time of entry. In order to display an instruction, the machine code is disassembled and the instruction mnemonic and operands are displayed. All valid instructions are translated.

The ASM command allows the user to create, modify, and debug MC6805 code. No provision is made for line numbers or labels.

Assembler input must have exactly one space between the mnemonic and the operand. There must be no space between the operand and the index specification ( ,X) except in the case of indexed no offset. Assembler input must be terminated by a carriage return. No comments, etc., are allowed after the instruction input.

EXAMPLE:

a .. ?LDA ,X b. ?STA 10,X c. ?BRCLR 3,$52,200 d. ?COMX e. ?CMP 200

After each new assembler input line, the new line is disassembled for the user before stepping to the new instruction. '!he new line may assemble to a different number of bytes than the previous one. It is left to the user to watch for this.

Each of the instruction pairs ASLA/LSLA and ASLX/LSLX have the same opcode, so disassembly always reveals LSLA or LSLX, respectively.

A dollar sign ($) may precede any number input except bit specifications in the BCLR/BSET and BRCLR/BRSET assembler mnemonics.

The assembler is terminated by entering a period (.) followed by a carriage return. Entering a carriage return alone on an input line steps to the next instruction.

Entering crRL X cancels an input line. '!he moni tor remains in the assembler roode.

EXAMPLE

?ASM 200 0200 FF STX ,X ?BRSET 7,10,210 0200 OE 10 OD BRSET 7,$10,$0210 0203 FF STX ,X ?LOA #$55 0203 A6 55 LOA #$55 0205 FF STX ,X ?STA ,X 0205 F7 STA ,X 0206 FF STX ,X ?LOX 654 0206 CE 06 1:11 LDX $0654 ";":1;

3.6.6 Block Fill Memory with Data BF

BF <addressl> <address2> <data>

where:

addressl Is the lower limit for fill operation.

address2 Is the upper limit for fill operation.

data Is the fill pattern hexadecimal value.

'!he BF corrmand allows the user to repeat a specific pattern throughout a determined user memory range.

Caution should be used when modifying locations O-F or 60-7F. The user I/O configurations and interrupt masks are located at O-F. 60-7F contain the user stack area. The user registers are stored in the five bytes immediately below the user stack.

No operation is performed if addressl is greater than address2.

EXAMPLE

?BF 101 200 FF

?BF 10 10 0

C(}1MENTS

Fill each byte of memory from 101 through 200 with the pattern FF.

Sets location 10 to o.

3-9

3.6.7 Breakpoint Set Breakpoint Remove

BR [<address>] ••• NOSR [<address>]

BR NOSR

The BR corrunand enters the address into the internal breakpoint table. During execution of the user program, a debug halt occurs immediately preceding the execution of any instruction address in the breakpoint table.

The NOBR command is used to remove one or all breakpoints from the breakpoint table.

User should not put a breakpoint on an SWI instruction as this is the instruction that the monitor uses to breakpoint/single-step a user program. The user may use the SWI instruction in the user program.

When a new breakpoint is entered, the breakpoint table is fi rst cleared. A maximum of three breakpoints may be set.

After setting or removing a breakpoint, the current breakpoint addresses, if any, are displayed~

CavlMAND FORMAT DESCRIPTION

BR Display all current breakpoints.

BR <address> Set a breakpoint.

BR <addressl> <address2> ••• Set several breakpoints.

NOBR Remove all current breakpoints.

NOBR <address> Remove a breakpoint.

EXAMPLE CCtJlMENTS

?SR 080 Sets a breakpoint at 080.

?BR 084 09A 984 Sets three breakpoints.

?NOBR Removes all breakpoints.

?BR Displays all current breakpoints.

3.6.8 Go (Execute program) G

G [<address>]

where:

address Is the starting address where execution begins.

The G command allows the user to initiate user program execution in free run in real time. The user may optionally specify a starting address where execution is to begin. Execution starts at current PC unless starting address is specified. Program execution continues until a breakpoint is encountered or the ABORT switch is pressed.

EXAMPLE

?G Begin execution at current PC location.

?G 100 Begin execution at location 100.

3-11

3.6.9 Download Memory (S-Records) from Host File Lew)

LOAD [<offset>]<=text>

where:

offset

=text

Is the optionally specified offset to be applied to all load addresses retrieved from the loaded S-records.

The text following the = is a host command sent to the host port, which instructs the host to download S-records.

The load command moves object data in S-record format (see Appendix A) from an external host to memory.

When loading data from a host file, the data received by the monitor is echoed to the terminal so that the user may monitor the load progress. 8-records are not echoed to the printer due to timing considerations. If the terminal is running at a baud rate less than the host, the S-record echo may be scrambled but the data is entered correctly to memory.

As the moni tor processes only valid S-record data, it is possible for the monitor to hang up during a load operation (there is no internal timeout because the terminal and host may be running at different baud rates) ~ Therefore: prior to the load operation, the user should define a reset vector to execute a branch-to-self instruction. Then, if the monitor should become hung up during a load operation, the user may do a reset/abort on the processor and return the monitor to the command state.

The load operation may optionally specify an offset to be applied to all load addresses retrieved from the loaded S-records. No check is made that the address does not rollover from high memory to low memory after adding the offset.

EXAMPLE

?LOAD =COPY FILE.LX:l,#CN

?LOAD lOO=COPY FILE.MX;#

CC»1AND

Loads the data from the host (EXORciser) to the EVM.

Loads; with offset; the data from th.e host (EXORmacs) to the EVM.

3.6.10 Memory Display MD

MD <addressl> [<address2>]

where:

addressl Is the beginning address of the memory to be displayed.

address2 Is the ending address of the memory to be displayed.

The MD command is used to display a section of memory beginning at addressl and continuing to address2. If address2 is not entered I 16 bytes are displayed beginning at addressl.

No operation is performed if addressl is greater than address2.

EXAMPLE

?MD 100 110 100 OC 00 00 30 6D 28 OC 00 00 39 6E 10 02 80 00 00 ••• Om( ••• 9n ••••• 110 00 OF 11 CO 10 38 IE 3C 00 E4 4E 4E OC 00 00 41 ••• @.8.<.dNN ••• A

3-13

3.6.11 Memory Modify (Interactive) MM

MM <address>

where:

address Is the memory location at which to start display/modify.

The MM command allows the user to examine/modify user memory locations in an interactive manner.

Caution should be used when modifying the user stack area because the user registers are stored in the five bytes immediately below the user stack.

Once entered, the MM command has several submodes of operation that allow modification and verification of data. '!he following terminators are recognized.

[<data>] (CR) - Update location and sequence forward.

[<data>]~(CR) - Update location and sequence backward.

[<data>] = (CR) - Update location and reopen same location.

[<data>] • (CR) - Update location and terminate.

An entry of only ". (CR) " terminates the register modify interactive mode.

CTRL X may be used to cancel any input line; the moni tor remains in the MM conunand.

EXAMPLE

?MM 100 OlOO=FF?OO= 0100=00? OlOO=FF?OO= 0100=00?-. -

3.6.13 Printer Attach Printer Detach

PA NOPA

PA NOPA

The PA command allows the user to software attach the line printer so that information sent to the terminal is also printed. The printer is physically attached to EVM J9 (PRINTER).

The NOPA command allows the user to detach the printer from the terminal.

The PA command should only be entered when a printer is physically connected to the EVM. Otherwise, the monitor hangs up while waiting for a response from the printer. To recover from this hang up , the printer must be attached, the power removed from the EVM, or the MASTER RESET switch (S5) pressed.

3-16

3.6.14 Program EPROM PRCG

PRO;

The PROG command is used to program the MC1468705 MCU internal EPROM. Prior to entering this command, jumpers must be positioned, switches must be set, and the unprogrammed MCU installed in the proper socket. paragraph 3.7 describes the procedure for programming the EPROM in detail. Because of the limited monitor memory size, only the MC1468705G2 can be programmed with the G2 version of the monitor program, and only the MC1468705F2 can be programmed with the F2 version of the monitor program.

The READ command allows the user to display the contents of the programmed internal EPROM of the MC1468705 MCU.

paragraph 3.8 describes the procedure for reading the programmed EPROM.

3-19

3.6.17 Register Modify (Interactive) RM

RM

The RM command is used to modify the MPU registers. The RM command takes no parameters and starts by displaying the S (stack pointer) register and then displaying the C (condition code) register and allowing changes to be made to the condition code register. The order of the register display follows:

S (stack pointer) - No modification allowed; moves to next line.

C (condition code) - Only bits 0-4 are significant.

A (user A register)

X (user X register)

p (program counter) - Two, bytes displayed/allowed.

The user may not change the stack pointer using the RM command.

Once entered, the RM command has several subnodes of operation that allow modification and verification of data. The following terminators are recognized.

[<data>] (CR) - Update register and sequence forward.

[<data>] A (CR) - Update register and sequence backward.

[<data>] = (CR) - Update register and reopen same location.

[<data>] .- (CR) - Update register and terminate.

M entry of only II. (CR) II terminates the register modify interactive mode.

The user may use CTRL-X to cancel any input line; the monitor remains in this corrmand.

EXAMPLE

?RM S=7D C=OO?CC A=AA?FE= A=FE? X=10?77 P=0056?100" X=77? ?=RD Regs S=7D

P=0100

3-20

3.6.18 Trace T

T [<count>]

where:

count Is the number (in hexadecimal) of instructions to execute.

The T command allows the user to monitor program execution on an instruction-by­instruction basis. The user may optionally execute several instructions at a time by entering a count value (up to FF) • Execution starts at the current PC. The PC displayed with the event message is of the next instruction to be executed.

During the tracing operation, breakpoints are active and user program execution stops upon the PC encountering a breakpoint address. Depending upon the user program execution results, the monitor issues one of the following target status messages before displaying a prompt for the next user input.

Trace S=nn C=nn A=nn X=nn P=nnnn

Brkpt S=nn C=nn A=nn X=nn P=nnnn

The user should not try to trace an instruction that branches to itself (eege; BRCLR Y,XX,*). Because the monitor puts an SWIT instruction on the object of the branch, the instruction would never be executed. However, it would look to the user as if the instruction executes. The user may enter a G command while the PC points to this type of instruction as long as the instruction is not at a breakpoint address.

The monitor issues an error message if the user attempts to trace at an address that contains an invalid opcode.

3.6.19 Transparent Mode TM

TM [<exit character>]

where:

exit character Is the user entry to terminate the transparent mode.

The TM conunand connects the EVM host port to the terminal port, which allows direct conununication between the terminal and the host. All input/output between them is ignored by the EVM until the exit character is entered from the terminal.

When the TM command is entered, an exit character is entered following the TM (e.g., ?TM 1). The exit character can be any keyboard character (printable or non-printable). The default exit character is CTRL-A. When the user task is completed, the transparent roode is terminated by entering the same exi t character.

EXAMPLES

?1M MOOS =DIR

=CTRL-A ?

C~

Command followed by a carriage return. CTRL-A is default exit character. MOOS program entered.

Task complete. Enter exit character CTRL-A. Transparent mode terminated.

Command followed by exit character (1). MOOS program entered. Directory called up.

Task complete. Enter exit character (1). Transparent mode terminated.

3.6.20 Dump Memory to Cassette Tape TPDU

TPDU <addressl> <address2>

where:

addressl Is the beginning address of the memory to be dLUnped.

address2 Is the ending address of the memory to be dumped.

The TPDU corrunand outputs memory contents (S-records) (see Appendix A) from beginning address through ending addess to an audio cassette through EVM J7. The recording technique is unique to the EVM.

~hen dumpir~ data to cassette tape, the data generated by L~e rr~nitor is echoed to the terminal so that the user may monitor the dump process. S-records are not echoed to the printer due to timing considerations. If the terminal is running at a . baud rate less than the cassette (cassette runs at approximately 300 baud), the S-record echo is scrambled but the data is entered on the cassette tape correctly.

When saving data to cassette tape, the monitor writes a leader to the cassette tape. The leader takes approximately 15 seconds to write. Therefore, no data echo is seen on the screen during this delay. The leader allows the user time to start the cassette in record mode and not miss any data when loading memory back from cassette. A 4K memory dLUnp to the cassette takes approximately two minutes.

No operation is performed if the starting address is greater than the ending address.

3.6.21 Load Memory from Cassette Tape TPLD

TPLD [<offset>]

where:

offset Is the optionally-specified offset to be applied to all load addresses retrieved from the loaded S-records.

The TPLD command loads data in S-record format from cassette tape to memory.

The load operation may optionally specify an offset to be applied to all load addresses retrieved from loaded S-records. No check is made that the address does not rollover from high memory to low memory after adding the offset.

When loading data from cassette tape, the data received by the monitor is echoed to the terminal so that the user may moni tor the load process. S-records are not echoed to the printer due to timing considerations. If the terminal is running at a baud rate less than the cassette (cassette runs at approximately 300 baud), the S-record echo is scrambled but the data is entered to memory correctly. A 2K memory load from cassette tape takes approximately one minute.

Because the monitor processes only valid S-record data, it is possible for the monitor to hang up during a load operation (there is no internal timeout because the terminal and cassette may be running at different baud rates). Therefore, prior to the load operation, the user should define a reset vector to execute a branch-to-self instruction. Then, if the monitor should become hung up during a load operation, the user may do a reset/abort on the processor and return the monitor to the command state.

3.7 PROGRAMMING THE EPROM

The monitor firmware allows the user to program MC146870SG2 and MC146870SF2 internal EPROM (see paragraph 3.6.14). When the user wants to program the MCU internal EPROM, jumpers must be repositioned, switches set, and indicators observed. Refer to device data sheets for details of the internal EPROM.

Paragraph 3.8 describes the READ function and the read program.

It is assumed that the user program has been debugged and resides in the EVM memory.

The following steps are used to program the internal EPROM:

a. Check switches 83 and 84 at the lower right of the EVM to ensure that the switches are in the OFF position.

b. Connect -18 Vdc source (see paragraph 2.4.1).

c. On headers JlS, J16, and J17, remove the jumpers from between pins 1 and . 2 and install between pins 2 and 3 (see paragraph 2.3.9).

d. Insert unprogrammed ~146870S into socket XUS6 for the 28-pin device, or socket XUS7 for the 40-pin device.

e. Position switch 84 (+SVOLT) to the ON position and observe LED indicator 084 is lit ..

f. Position switch 83 (PROGRAM) to the ON position and observe LED indicator 083 is lit.

g. Enter the command PROG (see paragraph 3.6.14).

h. LED indicator PROG (081) lights while programming is in progress. Approximately one second later, LED indicator VERF (082) lights, indicating the transfer has been verified. A monitor prompt (?) indicates progra.rp/verify function is cOIPplete; If the VERF indicator does not light, the programming is not correct. It is recommended that a second attempt at programming the same part be made. This is often successful when verification fails.

i. position switches 83 and 84 to the OFF position.

j. Remove the prograrrmed device. program additional devices.

Repeat the procedure f rom step d to

k. When programming task is complete, position the jumpers on headers JlS, J16, and J17 to pins 1 and 2.

3-25

3.8 READING THE EPROM CONTENTS

The monitor firm\alare allot;.'S the user to read the contents of the progra~ed EPROM. A special dump program must be included with the user program in memory to be transferred to the EPROM. Approximately 30 bytes of memory are requi red for the dump program. This dump program may be relocated anywhere in the valid EPROM space by changing the reset vector from 80 to the new start location. Caution must be used in calculating branch offsets since this dump program executes from EPROM and cannot be debugged by the monitor. The dump program (listed in Figure 3-3) is written for an MCl468705G2 (reset vector at IFFE-IFFF).

User I/O bit PC3 must not be held low by the user application circuitry during reset. After reset, all user I/O is available for applications (see Figure 3-2).

The dump program for the MCl468705F2 is available with the F2 monitor program.

The procedure to perform the READ function is as follows.

NOTE

It is important that user circuitry connected to I/O connector Jl does not pull down any of the user port lines during programming or reading. Full CMOS levels are necessary on these lines.

a. Check switches S3 and S4 at the lower right of the EVM to assure that the switches are in the OFF position.

b. On headers J15, J16, and J17, remove the jumpers from between pins 1 and 2 and install between pins 2 and 3 (see paragraph 2.3.9) •

c. Insert programmed r~1468705 into socket XU56 for the 28-pin device, or socket XU57 for the 40-pin device.

d. Position switch S4 (+5VOLT) to the ON position and observe LED indicator DS4 is lit.

e. Enter the command READ (see paragraph 3.6.16) •

f. The monitor displays the prompt (?) when the READ function is complete.

g. Position switch S4 to the OFF position.

h. Remove the programmed device. Repeat the procedure from step c to read additional devices.

i. When read task is completed, position the jumpers on headers J15, J16, and J17 to pins 1 and 2.

CHAPTER 4

FUNcrIONAL DESCRIPTION

4 .. 1 INTRODUcrI rn

This chapter provides a block diagram description of the EVM module. A block diagram is shown in Figure 4-1.

4.2 BLOCK DIAGRAM DESCRIPTION

The EVM is designed to simulate an MC1468705 MCU with the resident MC146805G2. Data transfer within the EVM is controlled by the monitor ROM firmware controlled from an external R8-232C compatible user terminal. The contents ,of the monitor ROM are not available to the user.

After system initialization, the EVM waits for a comnand line input from the user terminal. When a proper command is entered, the operation continues in one of tv.u basic IOOdes. If the command causes execution of a user program, the rooni tor mayor may not be reentered, depending on the desire of the user. For the alternate case, the command is executed under control of the monitor, and the system returns to a waiting condition after conunand completion. During command execution, additional user input may be required, depending on the command function.

rrhe monitor requires five bytes of user stack for user register storage upon monitor (re) entry. No limitation is placed on the user as to other uses of the stack.

All user reg isters are in an unknown state on monitor power-up.

4.2.1 Decode and Map SWitch Logic

The EVM operates in either one of two maps (monitor map or user map) (see Figure 3-1). The monitor map contains 4K bytes of RAM/ROM, which includes a user stack pointer, a monitor control register, monitor I/O, monitor RAM/stack, and the roonitor ROM. The user map contains the user I/O ports, user RAM/stack, and user pseudo ROM. A temporary map switch which allows modification of user memory, and a permanent switch which allows execution of user programs are provided on the EVM.

Temporary Map SWitch

The temporary map switch executes any three-byte instruction in the user map and returns irrmediately to the monitor map. The opcode and operand are fetched from the monitor map, maps are switched, and the instruction is executed in user space. Maps are switched automatically back to the monitor map at the beginning of the next load instruction register (LIR) from the processor.

4-1

The permanent map switch is initiated by conunand from the monitor, or by the USER RESET switch. Return to the monitor occurs at a breakpoint, at the end of a trace function in the monitor, or the ABORT switch.

The return from interrupt (RTI) opcode is fetched from the monitor map, maps are switched, and the registers are fetched from the user stack. Execution proceeds from the program counter (PC) fetched from the user stack.

When the USER RESET switch is pressed, the MCU and all user I/O are reset, maps are immediately switched to the user map, and the reset vector is fetched from the user map by the MCU. Breakpoints are ignored during this mode of execution.

Execution of user code continues until an SW! is decoded on the data bus during an LIR, and either the breakpoint flip-flop is set or the ABORT switch is pressed. '!be map is switched back to the monitor map after the registers are saved on the user stack. An SW[ which occurs when no breakpoint is set -- and when the ABORT swi tch is not be ing pressed -- does not cause a map swi tch. This allows user SWI's to be executed in real time.

'!be ABORT switch, when pressed, forces an SWI on the data bus until the next LIR. '!be reg isters are saved on the user stack and maps swi tched to the monitor. '!be ABORT switch has no effect on the monitor map.

When the USER RESET switch is pressed, the MCU and user I/O are reset into the user map. When the ABORT switch is pressed while in the user map, the monitor map is reenetered.

4.2.2 Monitor I/O

'!be monitor I/O consists of two serial R8-232C ports, a cassette port, and a parallel printer port.

Terminal Port

'!be terminal port communicates with an RS-232C compatible terminal in character mode. Baud rates are selectable through the use of a jumper on header J12. A software transparent mode allows direct cOImlunications between the terminal and the host.

H:>st Port

'!be host port provides downloading of 8-records from an RS-232C compatible host computer (EXORciser or any modem). Baud rates are selectable through the use of a jumper on J12.

Cassette Port

The cassette port provides a means of dumping and loading S-records to and from an audio cassette recorder. '!be recording technique is unique to the EVM.

4-2

Printer Port

The printer port interfaces with any standard Centronics type parallel printer. Seven data lines, strobe, and acknowledge are the only signal lines supported. When the printer port is activated, all information sent to the terminal is echoed to the printer.

4.2.3 User Map Area

The user map area consists of the user RAM/stack and the user pseudo ROM.

User RAM!Stack

The user stack is resident in memory from OIO-07F. The stack pointer value is displayed when trace and breakpoint functions are executed. For detailed information on the stacking order, see the specific device data sheet.

User Pseudo RCM

The user program space 080-FFF is RAM, which is write protected during user program execution. 'Ibis feature requires all programs to be RCXV1able and protects against program errors which would otherwise overwrite the program space.

A jumper on header Jl8 provides selection of a 2K-byte user map for evaluating the MC1468705. Vectors fetched from 7FS-7FF in the user program appear to the resident MCU at IFFS-IFFF. 'Ibis is accomplished by shadowing the lower 2K map into the upper 6K bytes during this option.

4.2.4 User I/O Ports

All user I/O ports (A, B, c, D) are available in the user map for evaluation. All ports are reconstructed off chip except port C.

The on chip timer, AID, and interrupts are available to the user.

4.2.5 EPROM Programmer and Reader

The MCl468705 MCU devices have an internal boot programmer program. When the appropriate voltages are applied externally and reset is lifted, the boot program is entered by a vector. The program takes data from the EVM I/O ports and transfers the data into the internal EPROM of the MCU device.

The contents of the programmed EPROM may be read by the EVM. A small program can be added to the user code, which allows the contents of the EPRa-1 to be downloaded to EVM memory.

APPENDIX A

S-RECORD OUTPUT FORMAT

The S-record format for output modules was devised for the purpose of encoding programs or data files in a printable format for transportation between computer systems. '!be transportation process can thus be visually monitored and the S-records can be more easily edited.

S-RECORD CONTENT

When ,viewed by the user, S-records are essentially character strings made of several fields which identify the record type, record length, memory address, cooejoaca, and checksum. Each byte of binary data is encoded as a L-cnaracter hexadecimal number: the first character representing the high-order 4 bits, and the second the lo~rder 4 bits of the byte.

'!be 5 fields which comprise an S-record are shown below:

+--------+---------------+-------------+-----------------------+------------+ I type I record length I address I code/data I checksum I +--------+---------------+-------------+-----------------------+------------+

where the fields are composed as follows:

PRINTABLE FIELD CHARACTERS

type 2

record length 2

address LL k_ or 8 ~, v,

code/data 0-2n

checksum 2

CONTENTS

S-record type SO, Sl, etc.

'!be count of the character pai rs in the record, excluding the type and record length.

'!he 2- , 3- , or 4-byte address at which the data field is to be loaded into memory.

From ° to n bytes of executable code, memory­loadable data, or descriptive information. For compatibility with teletypewriters, some programs may limit the number of bytes to as few as 28 (56 printable characters in the S-record).

'!be least significant byte of the one's complement of the sum of the values represented by the pairs of characters making up the record length, address, and the code/data fields.

Each record may be terminated with a CR{LF/NULL. Additionally, an S-record may have an initial field to accommodate other data such as line numbers generated by some time-sharing systems.

Accuracy of transmission is ensured by the record length (byte count) and checksum fields.

A-I

S-RECORD TYPES

F.iaht tvnes of S-records hnve been defined to nccommodnte the severnl needs of --J--- -~ ... --- -- - -------.- ----.- ------ -------- -- ---------------- ---- -- ... ----- -----.- --

the encoding, transportation, and decoding functions. '!he various Motorola upload, download, and other record transportation control programs, as well as cross assemblers, linkers, and other file-creating or debugging programs, utilize only those S-records which serve the purpose of the program. For specific information on which S-records are supported by a particular program, the user's manual for that program must be consulted. The EVM monitor supports only the Sl and S9 records. All data before the first Sl record is ignored. Thereafter, all records must be Sl type until the S9 record terminates data transfer.

An S-record-format module may contain S-records of the following types:

SO The header record for each block of S-records. The code/data field may contain any descriptive information identifying the following block of S-records. The address field is normally zeroes.

Sl A record containing code/data and the 2-byte address at which the code/data is to reside.

S2 A record containing code/data and the 3-byte address at which the code/data is to reside.

S3 A record containing code/data and the 4-byte address at which the code/data is to reside.

S5 A record containing the number of Sl, S2, and S3 records transmitted in a particular block. This count appears in the address field. There is no code/data field.

S7 A termination record for a block of S3 records. The address field may optionally contain the 4-byte address of the instruction to which control is to be passed. There is no code/data field.

S8 A termination record for a block of S2 records. The address· field may optionally contain the 3-byte address of the instruction to which control is to be passed. There is no code/data field.

S9 A termination record for a block of Sl records. The address field may optionally contain the 2-byte address of the instruction to which control is to be passed. If not specified, the first entry point specification encountered in the object module input will be used. There is no code/data field.

Only one termination record is used for each block of S-records. S7 and S8 records are usually used only when control is to be passed to a 3- or 4-byte address. Normally, only one header record is used, although it is possible for multiple header records to occur.

A-2

CREATION OF S-RECORDS

S-record-format programs may be produced by several dump utilities, debuggers, or several cross assemblers or cross linkers.

Several programs are available for downloading a file in S-record format from a host system to an 8-bi t microprocessor-based or a 16-bi t microprocessor-based system.

EXAMPLE

Shown below is a typical S-record-forrnat module, as printed or displayed:

S006000048445218 Sl130000285F245F2212226AO00424290008237C2A Sl1300100002000800082629001853812341001813 Sl13002041E900084E42234300182342000824A952 S107003000144ED492 S9030000FC

The module consists of one SO record, four Sl records, and an S9 record.

The SO record is comprised of the following character pairs:

SO

06

00 00

48

S-record type SO, indicating that it is a header record.

Hexadecimal 06 (decimal 6), indicating that six character pairs (or ASCII bytes) follow.

Four-character 2-byte address field, zeroes in this example.

44 ASCII H, D, ap.d R - "HOR". 52

18 The checksum.

The first Sl record is explained as follows:

Sl S-record type Sl, indicating that it is a code/data record to be loaded/verified at a 2-byte address.

13 Hexadecimal 13 (decimal 19), indicating that 19 character pairs, representing 19 bytes of binary data, follow.

00 Four-character 2-byte address field; hexadecimal address 0000, where 00 the data which follows is to be loaded.

A-3

The next 16 character pairs of the first Sl record are the ASCII bytes of the actual program code/data" In this asse!1lbly language example i t.'I1e hexadecimal opcodes of the program are written in sequence in the code/data fields of the Sl records:

OPCODE

28 5F 24 5F 22 12 22 6A 00 04 24 29 00 08 23 7C

INSTRUCTION

BHCC $0161 BCC $0163 BHI $0118 BHI $0172 BRSET 0,$04,$012F BHCS $OlOD BR8ET 4,$23,$018C

(The balance of this code is continued in the code/data fields of the remaining 81 records, and stored in memory location 0010, etc.)

2A The checksum of the first Sl record.

The second and third 81 records each also contain $13 (19) character pairs and are ended with checksums 13 and 52, respectively. The fourth Sl record contains 07 character pairs and has a checksum of 92.

The 89 record is explained as follows:

89

03

00 00
