Timing for the Clearing of Interrupt Sources
The interrupt source flags should be cleared in the interrupt exception service routine. After
clearing the interrupt source flag, a certain amount of time is required until 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 three times after it has
been cleared, and then execute an RTE instruction.
