TMR5GIF — RC2IF TX2IF CTMUIF CCP2IF CCP1IF RTCCIF
bit 7 bit 0
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 TMR5GIF: Timer5 Gate Interrupt Flag bit
1 = Timer gate interrupt occurred (must be cleared in software)
0 = No timer gate interrupt occurred
bit 6 Unimplemented: Read as ‘0’
bit 5 RC2IF: EUSART Receive Interrupt Flag bit
1 = The EUSART receive buffer, RCREG2, is full (cleared when RCREG2 is read)
0 = The EUSART receive buffer is empty
bit 4 TX2IF: EUSART Transmit Interrupt Flag bit
1 = The EUSART transmit buffer, TXREG2, is empty (cleared when TXREG2 is written)
0 = The EUSART transmit buffer is full
bit 3 CTMUIF: CTMU Interrupt Flag bit
1 = CTMU interrupt occurred (must be cleared in software)
0 = No CTMU interrupt occurred
bit 2 CCP2IF: ECCP2 Interrupt Flag bit
Capture mode:
1 = A TMR register capture occurred (must be cleared in software)
0 = No TMR register capture occurred
Compare mode:
1 = A TMR register compare match occurred (must be cleared in software)
0 = No TMR register compare match occurred
PWM mode:
Unused in this mode.
bit 1 CCP1IF: ECCP1 Interrupt Flag bit
Capture mode:
1 = A TMR register capture occurred (must be cleared in software)
0 = No TMR register capture occurred
Compare mode:
1 = A TMR register compare match occurred (must be cleared in software)
0 = No TMR register compare match occurred
PWM mode:
Unused in this mode.
bit 0 RTCCIF: RTCC Interrupt Flag bit
1 = RTCC interrupt occurred (must be cleared in software)
0 = No RTCC interrupt occurred
