PIR2 REGISTER

This register contains the CCP2 interrupt flag bit.

Applicable Devices

61 62 62A R62 63 R63 64 64A R64 65 65A R65 66 67

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

PWM Mode

Unused in this mode

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.
