PIR1 Register
PIR1 – PERIPHERAL INTERRUPT REGISTER 1 (ADDRESS: 0Ch)
bit 7
EEIF: EEPROM Write Operation Interrupt Flag bit
1 = The write operation completed (must be cleared in software)
0 = The write operation has not completed or has not been started
CMIF: Comparator Interrupt Flag bit
1 = Comparator output has changed
0 = Comparator output has not changed
RCIF: USART Receive Interrupt Flag bit
1 = The USART receive buffer is full
0 = The USART receive buffer is empty
TXIF: USART Transmit Interrupt Flag bit
1 = The USART transmit buffer is empty
0 = The USART transmit buffer is full
Unimplemented: Read as ‘0’
CCP1IF: CCP1 Interrupt Flag bit

Compare Mode
PWM 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
1 = TMR1 register overflowed (must be cleared in software)
0 = TMR1 register did not overflow
Legend:
R = Readable bit
-n = Value at POR
TMR1IF: TMR1 Overflow Interrupt Flag bit
R/W-0
EEIF
1 = A TMR1 register capture occurred (must be cleared in software)
0 = No TMR1 register capture occurred
1 = A TMR1 register compare match occurred (must be cleared in software)
0 = No TMR1 register compare match occurred
Unused in this mode

CMIF
RCIF
R-0
W = Writable bit
‘1’ = Bit is set
TXIF

Note:
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
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
software should ensure the appropriate
interrupt flag bits are clear prior to
enabling an interrupt.
