PIE Register(s)
Depending on the number of peripheral interrupt sources, there may be multiple Peripheral Inter-
rupt Enable registers (PIE1, PIE2). These registers contain the individual enable bits for the
Peripheral interrupts. These registers will be generically referred to as PIE. If the device has a
PIE register, The PEIE bit must be set to enable any of these peripheral interrupts.
Although, the PIE register bits have a general bit location with each register, future devices may
not have consistent placement. Bit location inconsistencies will not be a problem if you use the
supplied Microchip Include files for the symbolic use of these bits. This will allow the Assem-
bler/Compiler to automatically take care of the placement of these bits by specifying the correct
register and bit name.
Note:
Bit PEIE (INTCON<6>) must be set to enable any of the peripheral interrupts.
