9.2
The PIR registers contain the individual flag bits for the
peripheral interrupts. Due to the number of peripheral
interrupt sources, there are three Peripheral Interrupt
Flag Registers (PIR1, PIR2 and PIR3).

PIR1: PERIPHERAL INTERRUPT REQUEST (FLAG) REGISTER 1
PSPIF: Parallel Slave Port Read/Write Interrupt Flag bit
1 = A read or a write operation has taken place (must be cleared in software)
0 = No read or write has occurred
ADIF: A/D Converter Interrupt Flag bit
1 = An A/D conversion completed (must be cleared in software)
0 = The A/D conversion is not complete
RC1IF: USART1 Receive Interrupt Flag bit
1 = The USART1 receive buffer, RCREG, is full (cleared when RCREG is read)
0 = The USART1 receive buffer is empty
TX1IF: USART Transmit Interrupt Flag bit
1 = The USART1 transmit buffer, TXREG, is empty (cleared when TXREG is written)
0 = The USART1 transmit buffer is full
SSPIF: Master 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)
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 (must be cleared in software)
0 = No TMR2 to PR2 match occurred
