bit 7 bit 0

bit 7 Unimplemented: Read as ‘0’

bit 6 CMIF: Comparator Interrupt Flag bit

(1)

1 = Comparator input has changed

0 = Comparator input has not changed

bit 5 Unimplemented: Read as ‘0’

bit 4 EEIF: EEPROM Write Operation Interrupt Flag bit

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

0 = Write operation is not complete

bit 3 BCLIF: Bus Collision Interrupt Flag bit

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

0 = No bus collision occurred

bit 2 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

bit 1 TMR3IF: TMR3 Overflow Interrupt Flag bit

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

0 = TMR3 register did not overflow

bit 0 ECCP1IF: ECCP1 Interrupt Flag bit

(1)

Capture mode:

1 = A TMR1 (TMR3) register capture occurred (must be cleared in software)

0 = No TMR1 (TMR3) 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:

Unused in this mode.

Note 1: This bit is only available on PIC18F4X8 devices. For PIC18F2X8 devices, this bit

is unimplemented and reads as ‘0’.

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
