PIE Registers

The PIE registers contain the individual enable bits for

the peripheral interrupts. Due to the number of

peripheral interrupt sources, there are five Peripheral

Interrupt Enable registers (PIE1, PIE2, PIE3, PIE4 and

PIE5). When IPEN = 0, the PEIE/GIEL bit must be set to

enable any of these peripheral interrupts.
