Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 7

OSCFIF: Oscillator Fail Interrupt Flag bit

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

= Device clock operating

bit 6

CMIF: Comparator Interrupt Flag bit(1)

= Comparator input has changed (must be cleared in software)

= Comparator input has not changed

bit 5

Unimplemented: Read as ‘0’

bit 4

EEIF: Data EEPROM/Flash Write Operation Interrupt Flag bit

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

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

bit 3

BCLIF: Bus Collision Interrupt Flag bit

= A bus collision occurred (must be cleared in software)

= No bus collision occurred

bit 2

HLVDIF: High/Low-Voltage Detect Interrupt Flag bit

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

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

bit 1

TMR3IF: TMR3 Overflow Interrupt Flag bit

= TMR3 register overflowed (must be cleared in software)

= TMR3 register did not overflow

bit 0

ECCP1IF: ECCP1 Interrupt Flag bit(1)

Capture mode:

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

= No TMR1 register capture occurred

Compare mode:

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

= No TMR1 register compare match occurred

PWM mode:

Unused in this mode.

Note 1:

These bits are available in PIC18F4682/4685 and reserved in PIC18F2682/2685 devices.
