5. Operation
This section explains the operation of the interrupt request batch read.
Within each interrupt handler, the pertinent register is read to determine what bits are set. As a consequence,
what interrupt requests have been generated is found.
Note:
This register does not provide a function that can be used to input external interrupts.
Read registers EIRR0 and EIRR1, which are used to input external interrupts.
