ISP Hex record formats
Command/data function
Display device data or blank check
:05xxxx04sssseeeeffcc
Where
05 = number of bytes in the record
xxxx = required field but value is a don’t care
04 = function code for display or blank check
ssss = starting address, MSB first
eeee = ending address, MSB first
ff = subfunction
cc = checksum
Subfunction codes:
Example:
:0500000400001FFF00D9 (display from 0000H to 1FFFH)
Miscellaneous read functions
:02xxxx05ffsscc
Where:
02 = number of bytes in the record
xxxx = required field but value is a don’t care
05 = function code for miscellaneous read
ffss = subfunction and selection code
cc = checksum
Example:
:020000050000F9 (display manufacturer ID)
Direct load of baud rate
:02xxxx06HHLLcc
Where:
02 = number of bytes in the record
xxxx = required field but value is a don’t care
HH = high byte of timer T2
LL = low byte of timer T2
cc = checksum
Example:
:02000006FFFFcc (load T2 = FFFF)
00 = display data
01 = blank check
0000 = read manufacturer ID
0001 = read device ID 1
0002 = read device ID 2
0003 = read 6 /12 bit (bit 7 = 1 is 6 , bit 7 = 0 is 12 )
0080 = read boot code version
0700 = read security bits
0701 = read status bit
0702 = read boot vector
