PIC18F87K22 FAMILY
11.2
The PIR registers contain the individual flag bits for the
peripheral interrupts. Due to the number of peripheral
interrupt sources, there are six Peripheral Interrupt
Request (Flag) registers (PIR1 through PIR6).

PIR Registers
PSPIF: Parallel Slave Port Read/Write Interrupt Flag bit
1 = A read or write operation has taken place (must be cleared in software)
0 = No read or write operation 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: EUSART Receive Interrupt Flag bit
1 = The EUSART receive buffer, RCREG1, is full (cleared when RCREG1 is read)
0 = The EUSART receive buffer is empty
TX1IF: EUSART Transmit Interrupt Flag bit
1 = The EUSART transmit buffer, TXREG1, is empty (cleared when TXREG1 is written)
0 = The EUSART transmit buffer is full
SSP1IF: Master Synchronous Serial Port Interrupt Flag bit
1 = The transmission/reception is complete (must be cleared in software)
0 = Waiting to transmit/receive
TMR1GIF: Timer1 Gate Interrupt Flag bit
1 = Timer gate interrupt occurred (This must be cleared in software.)
0 = No timer gate interrupt occurred
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
TMR1IF: TMR1 Overflow Interrupt Flag bit
1 = TMR1 register overflowed (must be cleared in software)
0 = TMR1 register did not overflow

Note 1: Interrupt flag bits are set when an interrupt
2: User
condition occurs regardless of the state of
its corresponding enable bit or the Global
Interrupt Enable bit, GIE (INTCON<7>).
appropriate interrupt flag bits are cleared
prior to enabling an interrupt and after
servicing that interrupt.
