Section 6 Interrupt Controller (INTC)
6.3.1 Interrupt Priority Registers 01, 02, 06 to 16 (IPR01, IPR02, IPR06 to IPR16)
IPR01, IPR02, and IPR06 to IPR16 are 16-bit readable/writable registers in which priority levels
from 0 to 15 are set for IRQ interrupts, PINT interrupts, and on-chip peripheral module interrupts.
Table 6.3 shows the correspondence between the interrupt request sources and the bits in IPR01,
IPR02, and IPR06 to IPR16.
