15.1.10 Protection for Invalid Erase/Write
It should be taken care to the flash erase/write programming in code.
You must make preparations for invalid jump to the flash erase/write code by malfunction, noise, and
power off.
Note) For more information, please refer to the appendix “Flash Protection for Invalid Erase/Write”.
1. User ID check routine for the flash erase/write code.
ErWt_rtn:
---
MOV FIDR,#10100101B ;ID Code
MOV A,#ID_DATA_1 ;Ex) ID_DATA_1: 93H, ID_DATA_2: 85H, ID_DATA_3: 5AH
CJNE A,UserID1,No_WriteErase
MOV A,#ID_DATA_2
CJNE A,UserID2,No_WriteErase
MOV A,#ID_DATA_3
CJNE A,UserID3,No_WriteErase
MOV FMCR,#0x?? ;0x03 if write, 0x02 if erase

RET
No_WriteErase:
MOV FIDR,#00H
MOV UserID1,#00H
MOV UserID2,#00H
MOV UserID3,#00H
MOV Flash_flag,#00H
RET
If code is like the above lines, an invalid flash erase/write can be avoided.
NOTE) On flash memory erase and write, it should be disabled the RXE0/1 bit of USI0CR2/USI1CR2 register.
2. It is important where the UserID1/2/3 is written. It will be remain the invalid flash erase/write
problem if the UserID1/2/3 is written at the above line of the instruction “MOV
FIDR,#10100101B”. So. It had better writing the UserID1/2/3 in another routine after return.
Decide_ErWt:
---
MOV Flash_flag1,#38H ;Random value for example, in case of erase/write needs
MOV FSADRL,#20H ;Here 20H is example,
MOV Flash_flag2,#75H
