has been fetched and will be executed. This means this feature cannot be used on 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 delay branch instruction, the
break is generated prior to execution of the instruction that then first accepts the break.
Meanwhile, the break set for pre-instruction-break on delay slot instruction and post-
instruction-break on SLEEP instruction are also prohibited.
break condition is executed and then the break is generated prior to the execution of the next
instruction. As with pre-execution breaks, this cannot be used with overrun fetch instructions.
When this kind of break is set for a delay branch instruction, the break is generated at the
instruction that then first accepts the break.
There is thus no need to set break data for the break of the instruction fetch cycle.

This means that when address H'00001003 is set without specifying the size condition, for
example, the bus cycle in which the break condition is satisfied is as follows (where other
conditions are met).
