Interrupt Priority Registers A–H (IPRA–IPRH)

Interrupt priority registers A–H (IPRA–IPRH) are 16-bit readable/writable registers that set

priority levels from 0 to 15 for IRQ interrupts and on-chip peripheral module interrupts.

Correspondence between interrupt request sources and each of the IPRA–IPRH bits is shown in

table 6.4.
