PIC18F2480/2580/4480/4580
10.3 PIE Registers
The PIE registers contain the individual enable bits for
the peripheral interrupts. Due to the number of
peripheral interrupt sources, there are two Peripheral
Interrupt Enable registers (PIE1, PIE2). When IPEN = 0,
the PEIE bit must be set to enable any of these
peripheral interrupts.
