The Interrupt Priority (IPR) registers contain the individ-
ual 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 bit (IPEN) be set.
