Register Descriptions
19.3.1 Interrupt Priority Registers A to D (IPRA–IPRD)
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.
