ISP Hex record formats
Command/data function
Subfunction code = 04 (erase boot vector and status bit)
Subfunction code = 05 (program security bits)
Subfunction code = 06 (program status bit, boot vector, 6 /12 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, 0 kB to 8 kB, 00H
block 1, 8 kB to 16 kB, 20H
block 2, 16 kB to 32 kB, 40H
block 3, 32 kB to 48 kB, 80H
block 4, 48 kB to 64 kB, 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 6 /12 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])
