Section 4 Address Break
When an address break is set to an instruction as a branch destination of a conditional branch
instruction, the instruction set when the condition of the branch instruction is not satisfied is not
executed, and an address break is generated. Therefore an address break must not be set to the
instruction as a branch destination of a conditional branch instruction.
