19. Interrupt Controller (INTC)
19.3
19.3.1
Interrupt priority registers A to D (IPRA–IPRD) are 16-bit readable/writable registers that set
priority levels from 0 to 15 for on-chip peripheral module interrupts. IPRA to IPRC are initialized
to H'0000 and IPRD is to H'DA74 by a reset. They are not initialized in standby mode.
IPRA to IPRC
IPRD
Table 19.5 shows the relationship between the interrupt request sources and the IPRA–IPRD
register bits.
