Registers Of The Address Match Detection Function - Fujitsu MB90390 Series Hardware Manual

Registers of the Address Match Detection Function

The two types of registers for the address match detection function are as follows:
• Program address detection registers (PADR0, PADR1, PADR3 to PADR5)
• Program address detection control status register (PACSR0 and PACSR1)
■ Program Address Detection Registers (PADR0, PADR1, PADR3 to PADR5)
The program address detection registers compare the address with the value written in each register. If they
match when the interrupt permission bit corresponding to ADCSR is "1", the CPU is requested to issue the
INT9 instruction.
When the corresponding interrupt bit is "0", nothing occurs.
