4.3
When an address break is set to an instruction after a conditional branch instruction, and the
instruction set when the condition of the branch instruction is not satisfied is executed (see figure
4.3), note that an address break interrupt request is not generated. Therefore an address break must
not be set to the instruction after a conditional branch instruction.
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.
