Program Address Detection Registers (Padr0, Padr1) - Fujitsu MB90480 Series Hardware Manual

21.3.2 Program Address Detection Registers (PADR0, PADR1)

The value of an address to be detected is set in the program address detection
registers. When the address of the instruction processed by the program matches the
address set in the program address detection registers, the next instruction is forcibly
replaced by the INT9 instruction, and the interrupt processing program is executed.
