OSCFIF: Oscillator Fail Interrupt Flag bit

1 = System oscillator failed, clock input has changed to INTOSC (must be cleared in software)

0 = System clock operating

Unimplemented: Read as ‘0’

EEIF: Data EEPROM/Flash Write Operation Interrupt Flag bit

1 = The write operation is complete (must be cleared in software)

0 = The write operation is not complete or has not been started

Unimplemented: Read as ‘0’

LVDIF: Low-Voltage Detect Interrupt Flag bit

1 = A low-voltage condition occurred (must be cleared in software)

0 = The device voltage is above the Low-Voltage Detect trip point

TMR3IF: TMR3 Overflow Interrupt Flag bit

1 = TMR3 register overflowed (must be cleared in software)

0 = TMR3 register did not overflow

Unimplemented: Read as ‘0’

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
