IRQOUT is the same signal as the interrupt request signal to the CPU (see
figure 6.1). Thus, it is output when there is a higher priority interrupt request
than the one in the I3 to I0 bits of the SR.
When the accepted interrupt is sensed by edge, the IRQOUT pin becomes
high level at the point when the CPU starts interrupt exception processing
instead of instruction execution (before SR is saved to the stack).
If the interrupt controller has accepted another interrupt with a higher priority
and has output an interrupt request to the CPU, the IRQOUT pin will remain
low level.
