The address match interrupt can be set in eight ad- dresses. The AIERi bit in the AIER register determines whether the interrupt is enabled or disabled. The I flag and IPL do not affect the address match interrupt. Figure 11.12 shows registers associated with the address match interrupt. The starting address of an instruction must be set in the RMADi register. The address match interrupt does not occur when a table data or addresses other than the starting address of the instruction is set.
