The IPR registers contain the individual priority bits for
the peripheral interrupts. Due to the number of
peripheral interrupt sources, there are three Peripheral
Interrupt Priority Registers (IPR1, IPR2 and IPR3). The
operation of the priority bits requires that the Interrupt
Priority Enable (IPEN) bit be set.
