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 misc 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
LL = low byte of timer
cc = checksum
Example:
:02000007FFFFcc (load T2 = 7FFF)
Reset serial number
:xxxxxx07cc
Where:
xxxxxx = required field but value is a ‘don’t care’
07 = reset serial number function
