CCS C Compiler Manual PCB / PCM / PCH

#ID "filename"
#ID CHECKSUM
Elements:
Purpose:
Number 16 is a 16 bit number, number is a 4 bit number, filename is any valid
PC filename and checksum is a keyword.
This directive defines the ID word to be programmed into the part. This directive
does not affect the compilation but the information is put in the output file.
The first syntax will take a 16 -bit number and put one nibble in each of the four ID
words in the traditional manner. The second syntax specifies the exact value to be
used in each of the four ID words .
When a filename is specified the ID is read from the file. The format must be
simple text with a CR/LF at the end. The keyword CHECKSUM indicates the
device checksum should be saved as the ID.
