Posted on March 20, 2006 at 13:40Dear all,
We are able to achive functionality for, ''Read/Reset'', ''Program Word'', ''Block Erase'' and ''Chip Erase'' command for ST10F269.
But we are unlucky to achive functionality for ''Read Protection Status''.We are implementing this command as follow.
Read_Prot_Sts PROC
MOV R7,#00F0h ; Command Cycle 1 Of Read/Reset
EXTS R11,#01 ;Use EXTended Addressing for next MOV Instruction
MOV [R12],R7
MOV R5,#02a54h ; //Command Address
MOV R6,#015a8h ; //Command Address
SCXT dpp0,#08h
MOV R7,#00A8h ; Command Cycle 1
MOV [R5],R7
MOV R7,#0054h ; Command Cycle 2
MOV [R6],R7
MOV R7,#0090h ; Command Cycle 3
MOV [R5],R7
POP dpp0
MOV R13,[R12]
MOV R7,#00F0h ; Command Cycle 1 Of Read/Reset
EXTS R11,#01 ;Use EXTended Addressing for next MOV Instruction MOV [R12],R7 ;address id Don't care for Read/Reset Command
RET
Read_Prot_Sts ENDP
Is there any problem in above code? plz help us.
Thanks.....
Yogesh Gudekar.
