PIC18F2455/2550/4455/4550
9.5
The IPR registers contain the individual priority bits for
the peripheral interrupts. Due to the number of
peripheral interrupt sources, there are two Peripheral
Interrupt Priority registers (IPR1 and IPR2). Using the
priority bits requires that the Interrupt Priority Enable
(IPEN) bit be set.
