ICRs.
For an interrupt to be successfully processed, stack RAM must be available. A programmable chip select
is often used for the RAM, in which case, the RAM is not immediately available at startup. Thus, no
interrupts are recognized until PIVR is initialized. The RAM chip select and system stack should be set up
before this initialization.
If more than one interrupt source has the same interrupt priority level (IPL), the interrupt controller daisy
chains the interrupts with the priority order following the bit placement in the PIWR, with INT1 having
the highest priority and SWTO having the lowest priority, as shown in
7.2.1
This section describes the registers associated with the interrupt controller.
