11.10 Address Match Interrupt

The address match interrupt is non-maskable. This interrupt occurs immediately before executing the instruction

stored in the address specified by the RMADi register (i=0 to 7). Eight addresses can be set for the address match

interrupt. The AIERi bit in the AIER register determines whether the interrupt is enabled or disabled.

Figure 11.14 shows registers associated with the address match interrupt.

Set the starting address of the instruction in the RMADi register. The address match interrupt does not occur if a

table data or any address other than the starting address of the instruction is set.
