PIR Registers
The PIR registers contain the individual flag bits for the
peripheral interrupts. Due to the number of peripheral
interrupt sources, there are two Peripheral Interrupt
Request Flag registers (PIR1 and PIR2).
Note 1: Interrupt flag bits are set when an interrupt
condition occurs, regardless of the state of
its corresponding enable bit or the Global
Interrupt Enable bit, GIE of the INTCON
register.
2: User software should ensure the appropri-
ate interrupt flag bits are cleared prior to
enabling an interrupt and after servicing
that interrupt.

Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 7
PSPIF: Parallel Slave Port Read/Write Interrupt Flag bit(1)
1
= A read or a write operation has taken place (must be cleared by software)
0
= No read or write has occurred
bit 6
ADIF: A/D Converter Interrupt Flag bit
1
= An A/D conversion completed (must be cleared by software)
0
= The A/D conversion is not complete or has not been started
bit 5
RCIF: EUSART Receive Interrupt Flag bit
1
= The EUSART receive buffer, RCREG, is full (cleared when RCREG is read)
0
= The EUSART receive buffer is empty
bit 4
TXIF: EUSART Transmit Interrupt Flag bit
1
= The EUSART transmit buffer, TXREG, is empty (cleared when TXREG is written)
0
= The EUSART transmit buffer is full
bit 3
SSPIF: Master Synchronous Serial Port Interrupt Flag bit
1
= The transmission/reception is complete (must be cleared by software)
0
= Waiting to transmit/receive
bit 2
CCP1IF: CCP1 Interrupt Flag bit
Capture mode:
1
= A TMR1 register capture occurred (must be cleared by software)
0
= No TMR1 register capture occurred
Compare mode:
1
= A TMR1 register compare match occurred (must be cleared by software)
0
= No TMR1 register compare match occurred
PWM mode:
Unused in this mode
bit 1
TMR2IF: TMR2 to PR2 Match Interrupt Flag bit
1
= TMR2 to PR2 match occurred (must be cleared by software)
0
= No TMR2 to PR2 match occurred
bit 0
TMR1IF: TMR1 Overflow Interrupt Flag bit
1
= TMR1 register overflowed (must be cleared by software)
0
= TMR1 register did not overflow
Note 1: The PSPIF bit is unimplemented on 28-pin devices and will read as ‘0’.
