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 = Device oscillator failed, clock input has changed to INTOSC (bit must be cleared in software)
0 = Device clock is operating
bit 6-4
Unimplemented: Read as ‘0’
bit 3
BCLIF: Bus Collision Interrupt Flag bit
1 = A bus collision occurred (bit must be cleared in software)
0 = No bus collision occurred
bit 2
HLVDIF: High/Low-Voltage Detect Interrupt Flag bit
1 = A low-voltage condition occurred (bit must be cleared in software)
0 = The device voltage is above the regulator’s low-voltage trip point
bit 1
TMR3IF: TMR3 Overflow Interrupt Flag bit
1 = TMR3 register overflowed (bit must be cleared in software)
0 = TMR3 register did not overflow
bit 0
TMR3GIF: TMR3 Gate Interrupt Flag bit
1 = Timer gate interrupt occurred (bit must be cleared in software)
0 = No timer gate interrupt occurred
