PIC18FXX2
8.3
The PIE registers contain the individual enable bits for
the peripheral interrupts. Due to the number of periph-
eral interrupt sources, there are two Peripheral Inter-
rupt Enable Registers (PIE1, PIE2). When IPEN = 0,
the PEIE bit must be set to enable any of these
peripheral interrupts.
