Peripheral Interrupt Request (Flag) Registers
PSPIF: Parallel Slave Port Read/Write Interrupt Flag bit
1 = A read or a write operation has taken place
0 = No read or write has occurred
ADIF: A/D Converter Interrupt Flag bit
1 = An A/D conversion completed
0 = The A/D conversion is not complete
RCIF: USART Receive Interrupt Flag bit
1 = The USART receive buffer, RCREG, is full
0 = The USART receive buffer is empty
TXIF: USART Transmit Interrupt Flag bit
1 = The USART transmit buffer, TXREG, is empty
0 = The USART transmit buffer is full
SSPIF: Master Synchronous Serial Port Interrupt Flag bit
1 = The transmission/reception is complete
0 = Waiting to transmit/receive
CCP1IF: CCP1 Interrupt Flag bit
Capture Mode
1 = A TMR1 register capture occurred
0 = No TMR1 register capture occurred
Compare Mode
1 = A TMR1 register compare match occurred
0 = No TMR1 register compare match occurred
PWM Mode
Unused in this mode
TMR2IF: TMR2 to PR2 Match Interrupt Flag bit
1 = TMR2 to PR2 match occurred
0 = No TMR2 to PR2 match occurred
TMR1IF: TMR1 Overflow Interrupt Flag bit
1 = TMR1 register overflowed
0 = TMR1 register did not overflow
