Address Match Interrupt
2.15 Address Match Interrupt
Figure 1.20: Address match interrupt-related registers
An address match interrupt is generated when the address match interrupt address register contents
match the program counter value. Two 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).
Figure 1.20 shows the address match interrupt-related registers.
