PIR1 REGISTER
This register contains the individual ag bits for the
peripheral interrupts.
Applicable Devices
61 62 62A R62 63 R63 64 64A R64 65 65A R65 66 67
Note:
Interrupt ag 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 ag bits are clear prior to enabling an
interrupt.

CCP1IF: CCP1 Interrupt Flag bit
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
PWM Mode
Unused in this mode
bit 1:
TMR2IF: TMR2 to PR2 Match Interrupt Flag bit
1 = TMR2 to PR2 match occurred (must be cleared in software)
0 = No TMR2 to PR2 match occurred
bit 0:
TMR1IF: TMR1 Overow Interrupt Flag bit
1 = TMR1 register overow occurred (must be cleared in software)
0 = No TMR1 register overow occurred
Interrupt ag 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 ag bits are clear prior to
enabling an interrupt.
