* Interrupt requests that are designated as edge-detect type are held pending until the
The interrupt source flag should be cleared in the interrupt handler. To ensure that an
interrupt source that should have been cleared is not inadvertently accepted again, read
the interrupt source flag after it has been cleared, confirm that it has been cleared, and
then execute an RTE instruction.
interrupt requests are accepted. IRQ interrupts, however, can be cancelled by accessing
the IRQ status register (IRQSR). Interrupts held pending due to edge detection are
cleared by a power-on reset or a manual reset.
