10.3.1 Interrupt Priority Registers B to J (IPRB to IPRJ)
IPRB to IPRJ are 16-bit readable/writable registers in which priority levels from 0 to 15 are set for
on-chip peripheral module and IRQ interrupts. These registers are initialized to H'0000 by a
power-on reset or manual reset, but are not initialized in standby mode.
