Record type Command/data function
05
Miscellaneous Read Functions
:02xxxx05ffsscc
Where:
02 = number of bytes in the record
xxxx = required ï¬eld but value is a âdonât careâ
05 = function code for misc read
ffss = subfunction and selection code
0000 = read manufacturer id
0001 = read device id 1
0002 = read bootcode 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 ï¬eld but value is a âdonât careâ
HH = high byte of timer
LL = low byte of timer
cc = checksum
Example:
:02000007FFFFcc (load T2 = 7FFF)
07
Reset serial number
:xxxxxx07cc
Where:
xxxxxx = required ï¬eld but value is a âdonât careâ
07 = reset serial number function
cc = checksum
Example:
:00000001FF
08
Verify serial number
:nnxxxx08ss..sscc
Where:
xxxxxx = required ï¬eld but value is a âdonât careâ
08 = verify serial number function
ss..ss = serial number contents
cc = checksum
Example:
:03000008010203EF (verify s/n = 010203)
