CA4IF CA3IF TX2IF RC2IF R = Readable bit

bit0 W = Writable bit

-n = Value at POR reset

bit 7: SSPIF: Synchronous Serial Port (SSP) Interrupt Flag

1 = The SSP interrupt condition has occured, 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 / Master

A transmission/reception has taken place.

I2C Master

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 (Multimaster system).

A stop condition occurred while the SSP module was idle (Multimaster system).

0 = An SSP interrupt condition has occurred.

bit 6:

BCLIF: Bus Collision Interrupt Flag

1 = A bus collision has occurred in the SSP, when configured for I2C master mode

0 = No bus collision has occurred

bit 5:

ADIF: A/D Module Interrupt Flag

1 = An A/D conversion is complete

0 = An A/D conversion is not complete

bit 4: Unimplemented: Read as '0'

bit 3:

CA4IF: Capture4 Interrupt Flag

1 = Capture event occurred on RE3/CAP4 pin

0 = Capture event did not occur on RE3/CAP4 pin

bit 2:

CA3IF: Capture3 Interrupt Flag

1 = Capture event occurred on RG4/CAP3 pin

0 = Capture event did not occur on RG4/CAP3 pin

bit 1:

TX2IF:USART2 Transmit Interrupt Flag (State controlled by hardware)

1 = USART2 Transmit buffer is empty

0 = USART2 Transmit buffer is full

bit 0:

RC2IF: USART2 Receive Interrupt Flag (State controlled by hardware)

1 = USART2 Receive buffer is full

0 = USART2 Receive buffer is empty
