PIR1 Register
The PIR1 register contains the individual flag bits for
the peripheral interrupts.
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 bits are clear prior to enabling an
interrupt.
REGISTER 2-5:
PIR1 REGISTER (ADDRESS: 0Ch)
R/W-0
reserved
ADIF
reserved
SSPIF
CCP1IF
TMR2IF
TMR1IF
bit 7
bit 0
bit 7
Reserved: Always maintain these bits clear
bit 6
ADIF: A/D Converter Interrupt Flag bit
1
= An A/D conversion completed
0
= The A/D conversion is not complete
bit 5-4
Reserved: Always maintain these bits clear
bit 3
SSPIF: Synchronous Serial Port (SSP) Interrupt Flag
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:
SPI
- A transmission/reception has taken place
I2C Slave
- A transmission/reception has taken place
I2C Master
- A transmission/reception has taken place
- The initiated START condition was completed by the SSP module
- The initiated STOP condition was completed by the SSP module
- The initiated Restart condition was completed by the SSP module
- The initiated Acknowledge condition was completed by the SSP module
- A START condition occurred while the SSP module was idle (multi-master system)
- A STOP condition occurred while the SSP module was idle (multi-master system)
0 = No SSP interrupt condition has occurred
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
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
