2.7.18 Address Match Interrupt
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 af-
fected by the interrupt enable flag (I flag) and processor interrupt priority level (IPL). The value of the
program counter (PC) for an address match interrupt varies depending on the instruction being executed.
Figures 2.7.12 and 2.7.13 show the address match interrupt-related registers.

Nothing is assigned.
In an attempt to write to these bits, write “0”. The value, if read, turns out to
be indeterminated.
