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 0

OSCFIF: Oscillator Fail Interrupt Flag bit

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

0 = Device clock operating

Unimplemented: Read as ‘0’

EEIF: EEPROM or 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 = The supply voltage has fallen below the specified LVD voltage (must be cleared in software)

0 = The supply voltage is greater than the specified LVD voltage

Unimplemented: Read as ‘0’

CCP2IF: CCP2 Interrupt Flag bit

Capture mode:

1 = A TMR1 register capture occurred (must be cleared in software)

0 = No TMR1 register capture occurred

Compare mode:

1 = A TMR1 register compare match occurred (must be cleared in software)

0 = No TMR1 register compare match occurred

PWM mode:

Not used in this mode.
