Section 4 Address Break
When another interrupt request is accepted before an instruction to which an address break is set is
executed, exception handling of an address break interrupt is not executed. However, the ABIF bit
is set to 1 (see figure 4.4). Therefore the ABIF bit must be read during exception handling of an
address break interrupt.
