Legend:
R = Readable bit
u = Bit is unchanged
‘1’ = Bit is set
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
U = Unimplemented bit, read as ‘0’
-n/n = Value at POR and BOR/Value at all other Resets
HS = Hardware set

bit 6
bit 5-2
bit 1
bit 0
OSFIF: Oscillator Fail-Safe Interrupt Flag bit
1 = Oscillator fail-safe interrupt has occurred (must be cleared in software)
0 = No oscillator fail-safe interrupt
CSWIF: Clock Switch Complete Interrupt Flag bit
1 = The clock switch module indicates an interrupt condition (must be cleared in software)
0 = The clock switch does not indicate an interrupt condition
Unimplemented: Read as ‘0’
ADTIF: Analog-to-Digital Converter (ADC) Threshold Compare Interrupt Flag bit
1 = An A/D measurement was beyond the configured threshold (must be cleared in software)
0 = A/D measurements have been within the configured threshold
ADIF: Analog-to-Digital Converter (ADC) Interrupt Flag bit
1 = An A/D conversion or complex operation has completed (must be cleared in software)
0 = An A/D conversion or complex operation is not complete
Note:
Interrupt flag bits are set when an interrupt
condition occurs, regardless of the state of
its corresponding enable bit or the Global
Enable bit, GIE, of the INTCON register.
User software should ensure the
appropriate interrupt flag bits are clear
prior to enabling an interrupt.
