Section 6 Interrupt Controller (INTC)
6.3
6.3.1
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.
