Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘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.
