bit 7 bit 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
bit 7 OSCFIF: Oscillator Fail Interrupt Flag bit
1 = The device oscillator failed, clock input has changed to INTOSC (must be cleared in software)
0 = The device clock operating
bit 6 CM2IF: Comparator 2 Interrupt Flag bit
1 = The comparator input has changed (must be cleared in software)
0 = The comparator input has not changed
bit 5 CM1IF: Comparator 1 Interrupt Flag bit
1 = The comparator input has changed (must be cleared in software)
0 = The comparator input has not changed
bit 4 USBIF: USB Interrupt Flag bit
1 = USB has requested an interrupt (must be cleared in software)
0 = No USB interrupt request
bit 3 BCL1IF: Bus Collision Interrupt Flag bit (MSSP1 module)
1 = A bus collision occurred (must be cleared in software)
0 = No bus collision occurred
bit 2 HLVDIF: High/Low-Voltage Detect (HLVD) Interrupt Flag bit
1 = A High/Low-Voltage condition occurred (must be cleared in software)
0 = An HLVD event has not occurred
bit 1 TMR3IF: TMR3 Overflow Interrupt Flag bit
1 = The TMR3 register overflowed (must be cleared in software)
0 = The TMR3 register did not overflow
bit 0 CCP2IF: ECCP2 Interrupt Flag bit
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/TMR3 register compare match occurred (must be cleared in software)
0 = No TMR1/TMR3 register compare match occurred
PWM mode:
Unused in this mode.
