Address Match Interrupt 0
Address Match Interrupt 1
Address Match Interrupt 2
Address Match Interrupt 13
An address match interrupt is generated immediately before executing the instruction at the address indicated by
the RMADi register (i=0 to 3). Set the start address of any instruction in the RMADi register. Use the AIER0 and
AIER1 bits in the AIER register and AIER20 and AIER21 bits in the AIER2 register to enable or disable the
interrupt. Note that the address match interrupt is unaffected by the I flag and IPL. For address match interrupts, the
value of the PC that is saved to the stack area varies depending on the instruction being executed (refer to 12.5.7
Saving Registers).
(The value of the PC that is saved to the stack area is not the correct return address.) Therefore, follow one of the
methods described below to return from the address match interrupt.
Table 12.6 shows the Value of the PC that is Saved to the Stack Area when an Address Match Interrupt Request is
Accepted
Figure 12.13 shows the AIER, AIER2 and RMAD0 to RMAD3 Registers.

Rewrite the content of the stack and then use the REIT instruction to return.
Restore the stack to its previous state before the interrupt request was accepted by using the POP or similar
other instruction and then use a jump instruction to return.
