Conditions set:
A user break interrupt will occur before the instruction at address H'00000404. If it is possible
for the instruction at H'00000402 to accept an interrupt, the user break exception processing
will be executed after execution of that instruction. The instruction at H'00000404 is not
executed. The PC value saved is H'00000404.
Conditions set:
A user break interrupt does not occur because the instruction fetch cycle is not a write cycle.
Conditions set:
A user break interrupt does not occur because the instruction fetch was performed for an even
address. However, if the first instruction fetch address after the branch is an odd address set by
these conditions, user break interrupt exception processing will be carried out after address
error exception processing.
