Miscellaneous Read Functions
:02xxxx05ffsscc
Where:
02 = number of bytes in the record
xxxx = required eld but value is a ‘don’t care’
05 = function code for misc read
ffss = subfunction and selection code
0000 = read manufacturer id
0001 = read device id 1
0002 = read boot code version
0700 = read security bit (00 SoftICE serial number match 0 SB 0 Double Clock)
cc = checksum
Example:
:020000050000F9 (display manufacturer id)
06
Direct Load of Baud Rate
:02xxxx06HHLLcc
Where:
02 = number of bytes in the record
xxxx = required eld but value is a ‘don’t care’
HH = high byte of timer
LL = low byte of timer
cc = checksum
Example:
:02000006FFFFcc (load T2 = FFFF)
07
Reset serial number, erase user code, clear SoftICE mode
:xxxxxx07cc
Where:
xxxxxx = required eld but value is a ‘don’t care’
07 = reset serial number function
cc = checksum
Example:
:00000007F9
08
Verify serial number
:nnxxxx08ss..sscc
Where:
xxxxxx = required eld but value is a ‘don’t care’
08 = verify serial number function
ss..ss = serial number contents
cc = checksum
Example:
:03000008010203EF (verify s/n = 010203)
