PIR1 Register
The PIR1 register contains the individual flag bits for
the peripheral interrupts.
REGISTER 2-5:
PIR1 REGISTER (ADDRESS: 0Ch)
Note:
Interrupt flag bits get 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 bits are clear prior to enabling an
interrupt.

bit 7
PSPIF(1): 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
bit 6
ADIF: A/D Converter Interrupt Flag bit
1
= An A/D conversion completed
0
= The A/D conversion is not complete
bit 5
RCIF: USART Receive Interrupt Flag bit
1
= The USART receive buffer is full
0
= The USART receive buffer is empty
bit 4
TXIF: USART Transmit Interrupt Flag bit
1
= The USART transmit buffer is empty
0
= The USART transmit buffer is full
bit 3
Unimplemented: Read as ‘0’
bit 2
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.
bit 1
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
bit 0
TMR1IF: TMR1 Overflow Interrupt Flag bit
1
= TMR1 register overflowed (must be cleared in software)
0
= TMR1 register did not overflow
Note 1: PSPIF is reserved on the PIC16F870; always maintain this bit clear.
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
