PIR1 Register
This register contains the individual flag bits for the
Peripheral interrupts.
REGISTER 2-5:
PIR1: PERIPHERAL INTERRUPT FLAG REGISTER 1 (ADDRESS 0Ch)
U-0
R/W-0
U-0
U-0
ADIF
bit 7
Note:
Interrupt flag bits are 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 flag bits are clear prior to enabling an
interrupt.
R/W-0
SSPIF
R/W-0
CCP1IF
R/W-0
TMR2IF
R/W-0
TMR1IF
bit 0
bit 7
bit 6
Unimplemented:
Read as ‘0’
ADIF:
A/D Converter Interrupt Flag bit
1
= An A/D conversion completed
0
= The A/D conversion is not complete
Unimplemented:
Read as ‘0’
SSPIF:
Synchronous Serial Port (SSP) Interrupt Flag bit
1
= The SSP interrupt condition has occurred, and must be cleared in software before
returning from the Interrupt Service Routine.
The conditions that will set this bit are a transmission/reception has taken place.
0
= No SSP interrupt condition has occurred
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
TMR1IF:
TMR1 Overflow Interrupt Flag bit
1
= TMR1 register overflowed (must be cleared in software)
0
= TMR1 register did not overflow
bit 5-4
bit 3
bit 2
bit 1
bit 0
Legend:
R = Readable bit
- n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
