PIR1 Register
PIR1 REGISTER (ADDRESS 0Ch)
PSPIF
1 = A read or a write operation has taken place (must be cleared in software)
0 = No read or write has occurred
ADIF
1 = An A/D conversion completed (must be cleared in software)
0 = The A/D conversion is not complete
RCIF: USART Receive Interrupt Flag bit
1 = The USART receive buffer is full (clear by reading RCREG)
0 = The USART receive buffer is empty
TXIF: USART Transmit Interrupt Flag bit
1 = The USART transmit buffer is empty (clear by writing to TXREG)
0 = The USART transmit buffer is full
SSPIF: Synchronous Serial Port 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:
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)

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
