Legend:
R = Readable bit
-n = Value at POR
bit 7
Unimplemented: Read as ‘0’
RC2IF: USART2 Receive Interrupt Flag bit
1 = The USART2 receive buffer, RCREGx, is full (cleared when RCREGx is read)
0 = The USART2 receive buffer is empty
TX2IF: USART2 Transmit Interrupt Flag bit
1 = The USART2 transmit buffer, TXREGx, is empty (cleared when TXREGx is written)
0 = The USART2 transmit buffer is full
TMR4IF: TMR3 Overflow Interrupt Flag bit
1 = TMR4 register overflowed (must be cleared in software)
0 = TMR4 register did not overflow
CCPxIF: CCPx Interrupt Flag bit (ECCP3, CCP4 and CCP5)
Capture mode:
1 = A TMR1 or TMR3 register capture occurred (must be cleared in software)
0 = No TMR1 or TMR3 register capture occurred
Compare mode:
1 = A TMR1 or TMR3 register compare match occurred (must be cleared in software)
0 = No TMR1 or TMR3 register compare match occurred
PWM mode:
Unused in this mode.
