PIR1 REGISTER
TMR1GIF: Timer1 Gate Interrupt Flag bit
1 = Timer1 Gate is inactive
0 = Timer1 Gate is active
ADIF: A/D Converter Interrupt Flag bit
1 = A/D conversion complete (must be cleared in software)
0 = A/D conversion has not completed or has not been started
RCIF: USART Receive Interrupt Flag bit
1 = The USART receive buffer is full (cleared by reading RCREG)
0 = The USART receive buffer is not full
TXIF: USART Transmit Interrupt Flag bit
1 = The USART transmit buffer is empty (cleared by writing to TXREG)
0 = The USART transmit buffer is full
SSPIF: Synchronous Serial Port (SSP) Interrupt Flag bit
1 = The Transmission/Reception is complete (must be cleared in software)
0 = Waiting to Transmit/Receive
CCP1IF: CCP1 Interrupt Flag bit
Capture mode:
Compare mode:
PWM mode:
Unused in this mode
TMR2IF: Timer2 to PR2 Interrupt Flag bit
1 = A Timer2 to PR2 match occurred (must be cleared in software)
0 = No Timer2 to PR2 match occurred
TMR1IF: Timer1 Overflow Interrupt Flag bit
1 = The TMR1 register overflowed (must be cleared in software)
0 = The TMR1 register did not overflow
R/W-0
ADIF
1 = A TMR1 register capture occurred (must be cleared in software)
0 = No TMR1 register capture occurred
1 = A TMR1 register compare match occurred (must be cleared in software)
0 = No TMR1 register compare match occurred

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 of the INTCON register.
User
appropriate interrupt flag bits are clear prior
to enabling an interrupt.
