4. When an instruction fetch cycle is set, the break data register (BDR) is ignored. Therefore,
5. If the I bus is set for a break of an instruction fetch cycle, the setting is invalidated.
⎯ When a break condition is specified for the I bus, only the data access cycle is monitored.
⎯ Only data access cycles are issued for the internal DMA bus cycles.
⎯ If a break condition is specified for the I bus, even when the condition matches in an

break interrupt exception processing is set before or after the execution of the instruction can
then be selected with the PCB0 or PCB1 bit of the break control register (BRCR) for the
appropriate channel. If an instruction fetch cycle is set as a break condition, clear BA0 bit in
the break address register (BAR) to 0. A break cannot be generated as long as this bit is set to
1.
is confirmed that the instruction has been fetched and will be executed. This means a break
does not occur for instructions fetched by overrun (instructions fetched at a branch or during
an interrupt transition, but not to be executed). When this kind of break is set for the delay slot
of a delayed branch instruction, the user break interrupt request is not received until the
execution of the first instruction at the branch destination.
the break condition is executed and then the break is generated prior to execution of the next
instruction. As with pre-execution breaks, a break does not occur with overrun fetch
instructions. When this kind of break is set for a delayed branch instruction and its delay slot,
the user break interrupt request is not received until the first instruction at the branch
destination.
break data cannot be set for the break of the instruction fetch cycle.
Note: If a branch does not occur at a delayed branch instruction, the subsequent instruction is
