ISP hex record formats
Command/data function
Miscellaneous Write Functions
:nnxxxx03ffssddcc
Where:
nn = number of bytes in the record
xxxx = required field but value is a ‘don’t care’
ff = subfunction code
ss = selection code
dd = data (if needed)
cc = checksum
Subfunction code = 01 (Erase Blocks)
Subfunction code = 04 (Erase Boot vector and Status Bit)
Subfunction code = 05 (Program security bits)
Subfunction code = 06 (Program Status bit, Boot vector, 6x/12x bit)
Subfunction code = 07 (Chip Erase)
Subfunction code = 08 (Erase page, 128 B)
Example:
:0300000308E000F2 (erase page at E000H)
ff = 01
ss = block code, as shown below
block 0, 0k to 8k, 00H
block 1, 8k to 16k, 20H
block 0, 16k to 32k, 40H
block 0, 32k to 48k, 80H
block 0, 48k to 64k, C0H
ff = 04
ss = don’t care
ff = 05
ss = 00 program security bit 1
ss = 01 program security bit 2
ss = 02 program security bit 3
ff = 06
dd = data (for Boot vector)
ss = 00 program Status bit
ss = 01 program Boot vector
ss = 02 program 6x/12x bit
Erases code memory and security bits, programs default Boot vector and
Status bit
ff = 07
ff = 08
ss = high byte of page address (A[15:8])
dd = low byte of page address (A[7:0])
