3.3 Hardware Connection To realize parallel programming, part of connection between Programmer and Target MCU is fixed, which shows as Figure 3-1.

Figure 3-1: Connection between Programmer and Target MCU The Pin assignment of Target MCU is as below:

For communicating with Target MCU, some pins of Programmer must be assigned to match pins of Target MCU.

In this way, the HW connection is prepared, and then Programmer can control Target MCU to realize parallel programming.

4 Download Code to Target MCU

For parallel programming, a code must run in RAM of Target MCU, which accepts command and data from Programmer, and then erase flash, write data to flash of Target MCU, or read out data and send back to Programmer. So before Programmer can erase/write/read flash of Target MCU, must download the code to RAM of Target MCU.

4.1 PGM Mode Entry Timing Chart

The following timing will enable 8FX-LPC MCU enter PGM mode.


4.2 1-line UART Communication Specification 1-line UART features: Baud rate = 62500bps 8 bit data length 1 bit stop bit No parity LSB first All the communications are initialized by Programmer. That is, Programmer is Master and MCU is Slave during PGM mode. The 1-line UART between programmer and MB95F310/370 Series MCU is half-duplex, so data transfer is unidirectional.

Command frame is transferred from Programmer to MCU. Programmer is in sending status, while MCU is in receiving status;

Return frame is transferred from MCU to Programmer. Programmer is in receiving status, while MCU is in sending status;

Both command frame and return frame transfer at the same time is forbidden based on the 1-line UART communication.


4.3 The Communication Sequences Overview

4.4 Hand-shake Command After first power on entry, hand-shake with 8FX-LPC MCU is necessary before executing PGM command. The following is the hand-shank command: After first reset, PGM sends two bytes (0x55AA) to MCU repeatedly. There is an interval (�3ms) between 0x55 and 0xAA. Then PGM waits some time (�6.6ms) for the ACK from MCU. Repeating 20 times until ACK (0x51) is received.

If PGM receives 0x51 after sending 0x55AA commands, CR Trimming completes successfully.

If PGM receives no ACK (or ACK is not 0x51) in 20 times, hand-shake fails. Please power on 8FX-LPC MCU again and re-do the hand-shake operation.

0x55 <<interval>> 0xAA <<wait for ACK>> 0x55 <<interval>> 0xAA

0x55AA No ACK 0x55AA ---------- 0x55AA ACK(0X51) success

4.5 Command Format Overview

PGM can send commands to MCU only after hand-shake succeeds. They are fixed to 5 bytes for 1 unit, as shown below: Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Function Code Data H Data L Checksum ACK

Checksum is the sum of Function Code, Data H and Data L. Normal ACK value is 0x00; flash security ACK is 0xFD. Other ACK means operation error.

And then, Programmer can erase/write/read flash of Target MCU by sending command.

It means when the code runs in RAM of Target MCU, the preparative for the parallel programming is finished.


5 Basic Operation of Target MCU

For realize function of parallel programming, 3 basic operations are must: erase/write/read flash of Target MCU. When the code runs in RAM of Target MCU, these 3 basic operations can be implement by receiving and implementing command from Programmer.

To control Target MCU to erase/write/read, the following command must be sent by parallel port, and no 1-line UART command can be sent again.

5.1 Command Sending Sequence To send command to Target MCU, special format of command must be adopted by Programmer, the special format is shown in figure 5-1.

D1(Byte) D2(Byte) D3(Byte) D4(Byte) D5(Byte)

Command AddressH AddressL LengthH LengthL

Figure 5-1: Format of Command send

And Checksum = D1+D2+D3+D4+D5, which is used to check if command is received by Target MCU correctly, for how to use checksum, refer to 5.3 Erase Flash, 5.4 Write Flash, 5.5 Read Flash.

Dn: D1, D2, D3, D4 or D5

For Erase Command (0x55), D1 = 0x55

For Read Command (0x18), D1 = 0x18

For Write Command (0x81), D1 = 0x81.

To send one byte to Target MCU, must set PORT output, the timing of Erase Command send is shown in figure 5-2.

Figure 5-2: Timing of Erase Command send


The timing of Read Command send is shown in figure 5-3.

Figure 5-3: Timing of Read Command send The timing of Write Command send is shown in figure 5-4.

Figure 5-4: Timing of Write Command send


5.2 Data Send or Receive Sequence Here shows Programmer how to send/receive Data to/from Target MCU.

To send one byte data to Target MCU, Programmer must set PORT output, the timing is shown in figure 5-5.

Figure 5-5: Timing of send data To receive one byte data from Target MCU, Programmer must set PORT input, the timing is shown in figure 5-6.

Figure 5-6: Timing of receive data


5.3 Erase Flash Programmer sends Erase Flash command to Target MCU, and then Target MCU implement the command to Erase flash.

6 Flash Security Operation

1.1. Flash Security introduction

Write protection code “01H” to flash memory address (FFFCH), the flash security goes into effect immediately. After write code “01H” to address “FFFCH”, the next write/read operation will be denied. For example:

If write “01H” to address “FFFCH”, then write data to address “FFFDH” will not be executed. And the following verification will fail.

1.2. Flash Security Setting Suggestion

To avoid flash security error during programming, the recommended flash security setting sequence is: Write program to flash and force the data in address “FFFCH” is “FFH”, then do verify operation, after verification accessed, write “01H” to “FFFCH”, end programming.

1.3. Programming Flash Security Enabled MCU

If the flash security has been enabled in MCU, after power on, only hand-shake command and erase command can be accessed. Send other commands will receive the wrong ACK “0xFD” (security error). So if received ACK “0xFD” during programming, it is recommended to inform user that flash security has been enabled or send the erase command.
