instruction exists. Otherwise, a break condition will not be satisfied.
RTE instruction are placed immediately prior to the address specified by BAR, a prefetch
signal to the address may be output to request an address break by executing these instruction.
It is necessary to take countermeasures: do not set a break address to an address immediately
after these instructions, or determine whether interrupt handling is performed by satisfaction of
a normal condition.
address. Therefore, the timing to enter the interrupt exception handling differs according to the
instructions at the specified and at prior addresses and execution cycles.
