SSP2IF BCL2IF RC2IF TX2IF TMR4IF CCP5IF CCP4IF CCP3IF
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 SSP2IF: MSSP2 Interrupt Flag bit
1 = The transmission/reception is complete (must be cleared in software)
0 = Waiting to transmit/receive
bit 6 BCL2IF: MSSP2 Bus Collision Interrupt Flag bit
1 = A bus collision has occurred while the MSSP2 module configured in I
2
C™ master was
transmitting (must be cleared in software)
0 = No bus collision occurred
bit 5 RC2IF: EUSART2 Receive Interrupt Flag bit
1 = The EUSART2 receive buffer, RCREG2, is full (cleared when RCREG2 is read)
0 = The EUSART2 receive buffer is empty
bit 4 TX2IF: EUSART2 Transmit Interrupt Flag bit
1 = The EUSART2 transmit buffer, TXREG2, is empty (cleared when TXREG2 is written)
0 = The EUSART2 transmit buffer is full
bit 3 TMR4IF: TMR4 to PR4 Match Interrupt Flag bit
1 = TMR4 to PR4 match occurred (must be cleared in software)
0 = No TMR4 to PR4 match occurred
bit 2 CCP5IF: CCP5 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:
bit 1 CCP4IF: CCP4 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

bit 0 CCP3IF: ECCP3 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
