bit 7
Unimplemented: Read as ’0’
CMIF: Comparator Interrupt Flag bit
1 = Comparator input has changed
0 = Comparator input has not changed
Unimplemented: Read as’0’
EEIF: EEPROM Write Operation Interrupt Flag bit
1 = Write operation is complete (must be cleared in software)
0 = Write operation is not complete
BCLIF: Bus Collision Interrupt Flag bit
1 = A bus collision occurred (must be cleared in software)
0 = No bus collision occurred
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
TMR3IF: TMR3 Overflow Interrupt Flag bit
1 = TMR3 register overflowed (must be cleared in software)
0 = TMR3 register did not overflow
ECCP1IF: ECCP1 Interrupt Flag bit
Capture mode:
1 = A TMR1 (TMR3) register capture occurred
0 = No TMR1 (TMR3) register capture occurred
Compare mode:
1 = A TMR1 register compare match occurred
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
