TMS32010
Inleiding.
De TM532010 van Texas Instruments is een snelle 32-bits digitale signaalprocessor. T.I. heeft voor het ontwikkelen van programmatuur op deze processor een Evaluation Module, die moet worden gestuurd met een terminal en die als opslagoediu. een cassette­ recorder gebruikt. Zie voor het gebruik van de EVM de handleiding [11. Om deze EVM zo hand.aam mogelijk te gebruiken is een kop­ peling tot stand gebracht met een computer, die als in­ telligente terminal is geschakeld en die tevens functio­ neert als opslagmedium. Ais computer is gebruikt een Apple lIe [21 met een seriele interface (de z.g. super serial card [3]). De combinatie van Apple lIe, super serial card en het hierna beschreven controleprogramma vormt de TMS32010 Evaluation Module Controller.
De Communicatie.
De communicatie verloopt vol gens RS-232 in full duplex mode. De Apple lIe is daarvoor uitgebreid met een RS-232 uitgang. De super serial card, die deze interfacing verzorgt is op­ gebouwd rond het i.c. 6551, epn Asynchrone Communicatie Interface Adapter. Om twee redenen is echter geen gebruik gemaakt van de inge­ bouwde input- en outputroutines van de super serial card zel f. Ten eerste omdat het met deze card niet mogelijk bleek de maximale communicatie-snelheid van de EVM, nl. 19200 Baud, te bereiken. Ten tweede omdat de handshaking met de EVM niet overeenkomt met datgene .at is opgegeven in de hand­ leiding [11. Er is echter wei gebruik gemaakt van het op deze card aanwezige i.c. 6551. Door het direct aansturen van de 6551 met routines die zijn geschreven in assembler op de 6502 microprocessor is het mogelijk communicatie te bedrijven op 19200 Baud.

Gabruik van hat programma.
Het controleprogramma is een programma dat is geschreven in assembler voor de 6502 microprocessor [41. Het ver,orgt de communicatie van de Apple lIe met de EVM32010 via een 6551 ACIA op 19200 Baud, en organiseert tevens een aantal andere zaken. Zie voor gegevens van de ACIA 6551 de bijgevoegde data-sheets [51.
Het controleprogramma heeft de volgende mogelijkheden.
1. Terminal mode,
a. AIle toetsinformatie Mordt direkt overgezonden naar de EVM.
b. AIle van de EVM ontvangen karakters gaan naar de display.
2. Escape mode
a. De ontvangen karakters kunnen worden opgeslagen in het buffer.
b. Een reeks karakters kan worden uitgezonden vanuit het buffer.
c. De antvangen karakters kunnen al of niet worden geprint.
d. De inhoud van het buffer kan worden opgeslagen in een file op disk.
e. Het buffer kan worden gel aden vanuit een file op disk.
f. De inhoud van het buffer kan worden gemodificeerd.
g. Do inhoud van het buffer kan worden geprint.
h. Er kan een help-list met de commando's worden getoond.
-4-
Het programma werkt onder operating systeem DOS 3.3 [6). Het kan oak vanuit een hogere taal worden aangeroepen als subprogramma, waarbij dan de volgende CALL's kunnen wor­ den uitgevoerd.
CALL Warm_entry CALL lnit CALL Open_inbuf CALL Clos inbuf CALL Open_otbuf CALL Clos otbuf CALL Clr _e"iflg CALL Set_exiflg CALL WisJeglnr CALL Wis_linefd CALL Wis_commen CALL Print_help CALL Prt_buffer CALL Save_buff CALL Load buff - CALL Print_on CALL Print off
Start het programma inclusief volledige initialisatie. Start het programma zander initialisatie. Initialiseer het programma. Open het buffer voor input. Sluit het buffer voor input. Open het buffer voor output. Close het buffer voor output. Wis exit-vlag. Zet exit-vlag. Wis de regelnu_mers in het buffer. Wis de linefeeds in het buffer. Wis het commentaar in het buffer. Print de help-list. Print de inhoud van het buffer. Save de inhoud van het buffer op disk. Laad de inhoud van het buffer van disk. Zet de printer aan. Zet de printer uit.
Hierbij kunnen de volgende variabelen extern worden gelezen of gesc:hreven.
Edt_time CR-time Buffer _beg Buffer _end Buff er l,st
Timeout voor het verlaten van het programma. Timeout na een Carriage Return. Begin,dres van de bufferruimte. Eindadres van de bufferruimte. Laatst gebrui~te bufferadres.
Dit houdt in dat men b.v. vanuit BASIC het buffer kan vol­ schrijven met opdrachten voor de EVH, men kan de bufferout­ put activeren en naar de warm entry springen. Als men vooraf ook de 'exit-vlag zet wordt na een bepaalde tiaeout automa­ tisch het controleprogramma weer verlaten en vervolgt het BASIC programma [7). Als voorbeeld van een BASIC besturingsprograa.a wordt hierna de listing gegeven van programma EVH B.l.

Beschrijving van hat controleprogramma.
Het controleprogramma is geschreven in 6502 assembler voor de Apple lie. De abject-code begint op adres $8E41 en eindigt op $95FF juist voor het begin van DOS 3.3. Het buffer beslaat de geheugenruimte tussen $3000 en S8E40. Het programma heeft een cold-start op S8E41, en is opgebouwd als een Ius van routines die al of niet warden uitgevoerd. In deze Ius wordt gekeken of er een toets is ingedrukt, of de output vanuit het buffer aktief is en of er een karakter is ontvangen, terwijl er tevens een timer wordt bijgehouden. Indien een aktie wordt geconstateerd .ordt deze uitgevoerd en wordt de Ius vervolgd. Dit alles is te zien in het eerste blokschema. Indien de ESC-toets wordt ingedrukt komt het pro­ gramma in een andere mode, waarin het indrukken van een toets een specifieke funktie kan uitvoeren. Deze funkties zijn :
A Zet de printer adn. a Zet de printer uit. C Sluit het buffer voor input. o Sluit het buffer voor output. H Toon de help-list. I Open het buffer voor input. L Laad een file van disk in het buffer. o Open het buffer voor output. P Print de inhoud van het buffer. Q Verlaat het controleprogramma. S Save een file uit het buffer naar disk. V Wis het extra commentaar in het buffer. W Wis de regelnummers in het buffer. X Wis linefeeds in het buffer. Z Verlaat de ESC-mode.
Op de volgende bladzijden is in de vorm van een uitgebreid blokschema het verloop van het programma te volgen. Op het tweede blokschema is in detail de Escape-mode te zien. Verder is de assembler-listing van het programma gegeven met de bijbehorende verklaringen en een lijst met ad res sen van de gebruikte symbolen. De beide blokschema's geven samen met de asse.bler-listing een volledig inzicht in het programma.

R6551
DESCRIPTION The Rockwell A6551 Asynct'r"onous CommuniCaliorls Interface Adapter (ACtA) provides an easily implemented. program COl­
trolled interface between a-bit microprocessor-based systems and serial communication data sets and modems.
The ACtA has an Internal baud rale generator. ThiS feature elim­ inates the need lor mulllple component support CIrCUIts, a cryslal being the only other part required. The Transmitter baud rate can be selected under program control 10 be either 1 01 15 dif­ ferent rates from 50 to 19.200 baud. or al'h61imes an external clock rale. The ReceIver baud rate may be selected under pro­ gram control to be either the Transmitter rate. or at '1'6 limes the external clock rate. The ACtA has programmable word lengths of 5. 6, 7, or 8 bits: even, odd, or no parity: 1, 1 Vl. or 2 stop bits.
The ACtA is designed lor maximum programmed control from the microprocessor (MPU), to simplify hardware implementa­ tion. Three separate registers permit the MPU to easily select the R655"s operating modes and data Checking parameters and determine operaticrlal status.
The Command Register controls parity. receiWH echo mode, transmitter interrupt control, the state 01 the Ri"S line, receiver Interrupt control, and the stale of the DTR line.
The Control Register controls the number of stop bits. word length, receiver clock source, and baud rate
The Status Register IndICates the states of the IRQ. DSR, and DCD lines. Transmlner and Receiver Data Registers. and Overrun. Framing, and Parity Error conditIOns
The Transmitter and Receiver Data Registers are used lor tem­ porary dala storage by the ACIA Transmit and Receiver Circuits.

FUNCTIONAL DESCRIPTION " block diagram of the ACIA is presented in Figure 2 follOwed I:ly a description 01 each furctional element of the device.
DATA BUS BUFFERS
n. Dala Bus Buffer interfaces the system data Unes to the ntemaI data bus. The Data Bus Buffer is bi-directional. When It'e PJW line is high and the c~ is selected, the Data Bus Buffer passes the data from the system data Unes to the ACIA internal IjQ bus. When the RiW line is low and the chip is selected, the Data Bus Buffer writes the data from the internal data bus to the system dala bus.
NTERRUPT LOGIC
The Interrupllogir; will cause the IRQ hne to the microprocessor to go Ic.w when conditions are met that require the attention 01 lhe microprocessor. The conditions which can cause an inter­ rupt w~1 set bit 7 and the appropriate bit 01 bits 3 through 6 in !he Status Register, if enabled. Bits 5 and 6 correspond to the Data carrier Detect (OeD) logic and the Data Set Ready (DSR) lOgIC. Bits 3 and 4 correspond to the Receiver Data Register full hi the Transmitter Data Register empty conditions. These con­ cMions can cause an interrupt request if enabled by the Com­ mand Register.
VOCONTROL
The va Control Logic controls the se~tion of intemal registers 1'1 preparation for a data transfer on the internal data bus and Ihe direction of the transfer to or from the register.
The registers are selected by the Receiver Select (RSt, RSO) and ReaG-'Write (AIW) lines as described later in Table 1.
TIMING ANa CONTROL
The Timing and Control logic controls the liming 01 data trans­ fers on the internal data bus and the registers. the Data Bus Burter, and the microprocessor data bus, and the hardware reset features.
TIming is controlled by the system ~2 clock input. The Chip will perform data transfers to or from the microcomputer data bus dunng the;2 high period when selected.
All registers will be initialized by the Timing and Control logic when the Reset (RES) line goes low. See the individual register description for the state 01 the registers following a hardware reset.
TRANSMITTER AND RECEIVER DATA REGISTERS
These registers are used as lempOfClIY data storage lor the ACIA Transmit and Receive Circuits. Both the Transmitter and Receiver are selected by a Register Select 0 (RSO) and Register Select 1 (RS1) low condition. The Read/Write (WW) line deter­ mines which actually uses the internal data bus; the Transmitter Data Register is write only and the Receiver Data Register is read only.
Bit 0 is the first bit to be transmitted from the Transmitter Data Register (least signifICant bit first). The higher order bits follow in oreler. Unused bits in this register are "don't care".
The Receiver Data Register hOlds the first received data bit in bit 0 (least significant bit first). Unused high-order bits are "0". Parity bits are not contained in the Receiver Data Register. They are stripped off alter being used for parity checking.

STATUS REGISTER
The Status Register indicates the slate of interrupt condillons and other non-Interrupt status lines. The Interrupt conditions are the Data Set Ready, Data Carner Detect. Transmitter Data Reg­ Ister Empty and ReceIVer oala Register Full as reported in bits 6 through 3, respectively. If any of these bits are set. the Inter­ rupt (IRQ) indicator (bl' 7) IS also set. Overrun. Framing Error. and Panty Error are also reported (bits 2 through 0 respectively).

Parity Error (Bit 0). Framing Error (Bit 1). and Overrun (2)
None of these bits causes a processor interrupt to occur. but they are normally checked at the time the Receiver Data Aeg­ ister is read so that the validity of the data can be verified. These bits are self clearing (I.e., they are automatically cleared after a read of the Receiver Data Register).
Receiver Data Register Full (Bit 3)
This bit goes to a 1 when the ACtA transfers data from the Receiver Shift Register to the Receiver Data Register, and goes to a 0 (is cleared) when the processor reads the Receiver Data Register.
Transmitter Data Register Empty (Btl 4)
ThiS bit goes to a 1 when the ACtA transfers data from the Transrmtter Data Register to the Transmitter Shift Register, and goes to a 0 (IS cleared) when the processor writes new data onto the Transmitter Data Register.
Data Carrier Deleet (B" 5) and Data Set Ready (B" 6) These bits reflect the levels of the DCD and DSR inputs to the ACIA. A 0 indicates a low level (true condition) and a 1 indica!es a hlQh level (false). Whenever either of these inputs change state, an immediate processor interrupt (IAQ) occurs, unless bit 1 of the Command Register (lAD) is set to a 1 to disable IRO. When the interrupt occurs, the status bits indicate the lewis of the Inputs immediately after the change of state occurred. Sub­ sequent level changes will not affect the status bits until the Status RegISter is interrogated by the proceSSOf. At that time. another interrupt will immediately occur and the status t::cts reflect the new input levels. These bits are not automatically cleared (or reset) by an intemal operation.

Selected Baud Rate (Bits 0, 1, 2, 3)
These bits select the Transmitter baud rate, which can be at 1/'6 an external clock rate or one of 15 other rates controlled by the internal baud rate generator.
If the Receiver clock uses the same baud rate as the transmitter, then Axe becomes an output and can be ..Ised to slave other circuits to the ACIA. Figure 3 shows the Transmitter and Receiver layout.

Receiver Clock Source (Btl 4)
This bit controls the clock source to the Receiver. A 0 causes the Receiver to operate at a baud rate of iii, an external clock. A t causes the Receiver 10 operate al the same baud nne as is selected for the transmitter.
Word length (BHa 5, 6)
These bits determine the word length 10 be used (5. 6. 7 or 8 bits).
Stop BH Number (BH 7)
This bII determines the number 01 slop bits used. A 0 always indicates one stop bit. A 1 indICates 1'h stop bits if the word length is 5 with no parity selected, 1 stop bit if the word length is 8 with parity selected, or 2 stop bits in an other configurations.

Receiver Interrupt Control (Bh 1)
This bit disables the Receiver from generating an interrupt when set 10 a ,. The Receiver interrupt is enabled when this bit is set to aO and BitOiS set to a 1.
Transmitter Interrupt Control (Blta 2, 3)
These bits control the state of the Ready to Send (RTS) line- and the Transmitter interrupt.
Receiver Echo Mode (Bn 4)
A 1 enables the Receiver Echo Mode and a 0 enables the Receiver Echo Mode. When bit 4 is a 1, bits 2 and 3 must be O. In the Receiver Echo Mode, the Transmitter returns each transmissicn received by the Receiver delayed by one-haH bit time.
Parity Mode Enable (Bn 5)
This bit enables parity bit generation and checking. A 0 disables parity bit generation by the Transmitter and parity bit chectl:ing by the Receiver. A 1 bit enables generation and checking of parity bits.
Parity Mode Control (Bna 8, 7)
These bits determine !he type of parity generated by the Trans­ miner, (even, odd, mark or space) and the type of parity check done by the Receiver (even. odd, or no check).

Interrupt Roqueot QRQ)
The ~ pin is an interrupt output from the interrupt control logic. It -IS an open drain output, permitting several devices to be con­ nected to the common m microprocessor input, Normally a high level, IRQ goes low when an interrupt occurs.
Dot. BUI (DO-07)
The eight data line (00-07) pins transfer data between the pro­ cessor and the ACtA. These lines are bi-direclional and are nor­ mally high-impedance except during Read cycles when the ACIA is selected .

ACIAIMOOEM INTERFACE
Crystal Pins (XTLI, XTLO)
These pins are normally directly connected to the external crystal (1.8432 MHz) to denve the various baud rates. Alter­ natively. an externally generated clock can dnve the XTU pin. in whICh case 1he XTLO pin must Iloal. XTU is the input pin for the transmit clock.
Tran!NTIit Data (TxO)
The TxD output line translers serial nonreturn-to-Zero (NRZ) data to the modem. The least signifICant bit (lSB) of the Transmit Data Register IS the first data bll transmitted and the rate of data transmisSion is determined by the baud rate selected or under control of an external clock. This selectIOn IS made by program­ ming the Control Register.
Receive Data (RxD)
The AxD Input line transfers senal NRZ data Into the ACtA from the modem. lSB IlfSI. The receiver data rate IS either the pro­ grammed baud rate or under the contrOl of an externally gen­ erated receiver clock. The selectIOn IS made by programming the Control Register.
Receive Clock (RxC)
The R:o:C IS a bl-dlrectlOnal prn which is erther the receiver 16:0: clock Input or the receiver 16x clack output. The latter mode results " the Internal baud rate generator IS selected for receiver data clocking.
Request to Send (RTS)
The R'rn output pin controls the modem from the processor. The state 01 the ATS pin IS determined by the contents of the Command Register.
Cle.r to Send (CTS)
The CTS input pin controls the transmitter operatIOn. The enable state is with CfS low. The transmitter is automatically disabled if CTS is hIgh.
O.to Tormlnal Ready (DfII)
ThIS output pin indicates the status of the ACtA to the modem. A low on 5TA indICates the ACIA is enabled, a high indicates it is disabled. The processor controls this pin via bit 0 of the Command Register.
Dahl Set Ready (~)
The DSA input pin indicates to the ACIA the status 01 the modem. A low indicates the "ready" state and a high, "not­ ready."
o.t. C .... 1er Dstect (i5ClI)
The DeD mput pin indICates to the ACtA the status of the carrler­ detect output 01 the modem. A low indicates that the modem carner SlQnal is present and a high, thai it is not.
TRANSMITTER AND RECEIVER OPERATION
Continuous Data Tranamlt
In the normal operating mode, the interrupt request output (IRO) Signals when the ACtA is ready to accept the next data word 10 be transmitted. This interruPt occurs at the beginning of the Start Bit. When the processor reads the Status Register of the ACtA. the interrupt is cleared.
The processor must then identify that the Transmit Data Reg­ Ister is ready to be loaded and must then load it with the next data word. This must occur before the end of the Stop Bit, other­ wise a continuous "MARK" will be transmitted. Figure 5 shows the contrnuous Data Transmit timing relationship.

ContinuOUS Oat. Receive
$lmrlar to the Continuous Data Tra~if case, the normal OOIIratiol'1 01 this mode is to assert IRQ when the ACtA has -ecerved a full data word. This occurs al about 9/1$ point through !I'e StoP Bit. The processor must read the Status Aegister and
read the data word before thB next interrupt, oth&rw'lse the Overrun condition occurs. Figure 6 shows the continuous Oal8 Receive Timing Relationship.
