The Shared Interrupt Select (IRQSS) Register, shown in Table 48, determines the source
of the PADxS interrupts. The Shared Interrupt Select Register selects between Port A and
alternate sources for the individual interrupts.
Because these shared interrupts are edge-triggered, it is possible to generate an interrupt
just by switching from one shared source to another. For this reason, an interrupt must be
disabled before switching between sources.
