Patch program byte count
The total byte count of the patch program (main body) is stored. If the byte count is "00
no patch program is provided.
Detect address (24 bits)
The address where the instruction code is replaced by the INT9 instruction code due to program error is
stored. This address is set in the detection address setting registers (PADR0, PADR1).
Patch program (main body)
The program executed by the INT9 interrupt processing when the program address matches the detect
address is stored. Patch program 0 is allocated from any predetermined address. Patch program 1 is
allocated from the address indicating <starting address of patch program 0 + total byte count of patch
program 0>.
