PIR2 REGISTER

Applicable Devices

72 73 73A 74 74A 76 77

This register contains the CCP2 interrupt flag bit.

.

Note:

Interrupt flag bits get 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.

Capture Mode

1 = A TMR1 register capture occurred (must be cleared in software)

0 = No TMR1 register capture occurred

Compare Mode

1 = A TMR1 register compare match occurred (must be cleared in software)

0 = No TMR1 register compare match occurred

Unused

Interrupt flag bits get set when an interrupt condition occurs regardless of the state of its corresponding enable bit or the

global enable bit, GIE (INTCON<7>). User software should ensure the appropriate interrupt flag bits are clear prior to

enabling an interrupt.
