5.3.3
Interrupt priority level setting register C (IPRC) is a 16-bit read/write register that sets the priority
levels (0–15) of IRQ0–IRQ3 interrupts. IPRC is initialized to H'0000 by a reset. It is not initialized
in standby mode.
Bits 15 to 0–IRQ0 to IRQ3 Priority Level 3 to 0 (IRQnIP3–IRQnIP0, n = 0–3): These bits set the
IRQ0–IRQ3 priority levels. There are four bits for each interrupt, so the value can be set between
0 and 15.
