* Interrupt requests that are designated as edge-sensing are held pending until the
interrupt source flag, "time from occurrence of interrupt request until interrupt controller
identifies priority, compares it with mask bits in SR, and sends interrupt request signal to
CPU" shown in table 5.5 is required before the interrupt source sent to the CPU is actually
cancelled. To ensure that an interrupt request that should have been cleared is not
inadvertently accepted again, read the interrupt source flag after it has been cleared, and
then execute an RTE instruction.
interrupt requests are accepted. IRQ interrupts, however, can be cancelled by accessing
the IRQ interrupt request register (IRQRR). For details, see section 5.4.4, IRQ
Interrupts.
Interrupts held pending due to edge-sensing are cleared by a power-on reset.
