24. ROM correction function
When an address matches the value set in the address detection register, the instruction code to be loaded into
the CPU is forced to be replaced with the INT9 instruction code (01
H
) . When executing a set instruction, the
CPU executes the INT9 instruction. The ROM correction function is implemented by processing using the INT9
interrupt routine.
The device contains two address detection registers, each provided with a compare enable bit. When the value
set in the address detection register matches an address and the interrupt enable bit is “1”, the instruction code
to be loaded into the CPU is forced to be replaced with the INT9 instruction code.
