Interrupts
Address Match Interrupt
Figure 1.9.12. Address match interrupt-related registers
An address match interrupt is generated when the address match interrupt address register contents
match the program counter value. Four address match interrupts can be set, each of which can be enabled
and disabled by an address match interrupt enable bit. Address match interrupts are not affected by the
interrupt enable flag (I flag) and processor interrupt priority level (IPL). For an address match interrupt, the
value of the program counter (PC) that is saved to the stack area varies depending on the instruction being
executed. Note that when using the external data bus in width of 8 bits, the address match interrupt cannot
be used for external area.
Figure 1.9.12 shows the address match interrupt-related registers.
