24.5 Program Example of Address Match Detection Function

This section gives a program example for the address match detection function.
I Program Example for Address Match Detection Function
❍ Processing specifications
If the address of the instruction to be executed by the program matches the address set in the
detection address setting register (PADR0), the INT9 instruction is executed.
❍ Coding example
