SSPIF
SSPIF: Synchronous Serial Port (SSP) Interrupt Flag
1 = The SSP interrupt condition has occured, and must be cleared in software before returning from the
0 = An SSP interrupt condition has occurred.
BCLIF: Bus Collision Interrupt Flag
1 = A bus collision has occurred in the SSP, when configured for I
0 = No bus collision has occurred
ADIF: A/D Module Interrupt Flag
1 = An A/D conversion is complete
0 = An A/D conversion is not complete
Unimplemented: Read as '0'
CA4IF: Capture4 Interrupt Flag
1 = Capture event occurred on RE3/CAP4 pin
0 = Capture event did not occur on RE3/CAP4 pin
CA3IF: Capture3 Interrupt Flag
1 = Capture event occurred on RG4/CAP3 pin
0 = Capture event did not occur on RG4/CAP3 pin
TX2IF:USART2 Transmit Interrupt Flag (State controlled by hardware)
1 = USART2 Transmit buffer is empty
0 = USART2 Transmit buffer is full
RC2IF: USART2 Receive Interrupt Flag (State controlled by hardware)
1 = USART2 Receive buffer is full
0 = USART2 Receive buffer is empty
