Section 5 Interrupt Controller (INTC)
5.10
5.10.1
The interrupt source flags should be cleared in the interrupt exception service routine. After
clearing 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.
