2.2.2.6

PIE2 Register

The PIE2 register contains the individual enable bits for

the CCP2 peripheral interrupt, the SSP bus collision

interrupt, EEPROM write operation interrupt and the

comparator interrupt.

REGISTER 2-6:

PIE2 REGISTER (ADDRESS 8Dh)

Note:

Bit PEIE (INTCON<6>) must be set to

enable any peripheral interrupt.
