PIC18F6520/8520/6620/8620/6720/8720
9.3 PIE Registers
The PIE registers contain the individual enable bits for
the peripheral interrupts. Due to the number of
peripheral interrupt sources, there are three Peripheral
Interrupt Enable registers (PIE1, PIE2 and PIE3).
When the IPEN bit (RCON<7>) is ‘0’, the PEIE bit must
be set to enable any of these peripheral interrupts.

R = Readable bit
- n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared x = Bit is unknown
