2.12.2 Operation of Address Match Interrupt

The following is an operation of address match interrupt. Figure 2.12.4 shows the set-up procedure of

address match interrupt, and Figure 2.12.5 shows the overview of the address match interrupt handling

routine.

Operation (1) The address match interrupt handling routine sets an address to be used to cause the ad-

dress match interrupt register to generate an interrupt.

(2) Setting the address match enable flag to “1” enables an interrupt to occur.

(3) An address match interrupt occurs immediately before the instruction in the address indicated

by the address match interrupt register as a program is executed.
