PIC18CXX2
7.4
The IPR registers contain the individual priority bits for
the peripheral interrupts. Due to the number of periph-
eral interrupt sources, there are two Peripheral Inter-
rupt Priority Registers (IPR1, IPR2). The operation of
the priority bits requires that the Interrupt Priority
Enable (IPEN) bit be set.
