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: 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
0 = A low-voltage condition has not occurred
Unimplemented: Read as ‘0’

PTIF: PWM Time Base Interrupt bit
1 = PWM time base matched the value in PTPER register. Interrupt is issued according to the
postscaler settings. PTIF must be cleared in software.
0 = PWM time base has not matched the value in PTPER register
Unimplemented: Read as ‘0’
