CHAPTER 22 ADDRESS MATCH DETECTION FUNCTION
■ Functions of Detect Address Setting Registers
• There are six detect address setting registers (PADR0 to PADR5) that consist of a high byte (bank),
middle byte, and low byte, totaling 24 bits.
• In the detect address setting registers (PADR0 to PADR5), starting address (first byte) of instruction to
be replaced by INT9 instruction should be set.
