4.2
When the ABIF and ABIE bits in ABRKSR are set to 1, the address break function generates an
interrupt request to the CPU. The ABIF bit in ABRKSR is set to 1 by the combination of the
address set in BAR, the data set in BDR, and the conditions set in ABRKCR. When the interrupt
request is accepted, interrupt exception handling starts after the instruction being executed ends.
The address break interrupt is not masked by the I bit in CCR of the CPU.
Figures 4.2 show the operation examples of the address break interrupt setting.
