Address Match Interrupt
Address Match Interrupt
Figure 1.14.12. Address match interrupt-related registers
An address match interrupt is generated when the address match interrupt address register contents match
the program counter value. 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 inter-
rupt 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. Note that when using
the external data bus in width of 8 bits, the address match interrupt cannot be used for external area.
Figure 1.14.12 shows the address match interrupt-related registers.

In an attempt to write to these bits, write “0”. The value, if read, turns out to
be indeterminated.
