PIR2 Register
The PIR2 register contains the flag bits for the CCP2
interrupt, the SSP bus collision interrupt and the
EEPROM write operation interrupt.
.
REGISTER 2-7:
PIR2 REGISTER (ADDRESS: 0Dh)
Note:
Interrupt flag bits are set when an interrupt
condition occurs, regardless of the state of
its corresponding enable bit or the global
enable bit, GIE (INTCON<7>). User soft-
ware should ensure the appropriate inter-
rupt flag bits are clear prior to enabling an
interrupt.

BCLIF: Bus Collision Interrupt Flag bit
1
= A bus collision has occurred in the SSP, when configured for I2C Master mode
0
= No bus collision has occurred
