The IPR registers contain the individual priority bits for the
peripheral interrupts. Due to the number of peripheral
interrupt sources, there are five Peripheral Interrupt
Priority registers (IPR1, IPR2, IPR3, IPR4 and IPR5).
Using the priority bits requires that the Interrupt Priority
Enable (IPEN) bit be set.
