Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
â1â = Bit is set
U = Unimplemented bit, read as â0â
â0â = Bit is cleared
x = Bit is unknown

OSCFIF: Oscillator Fail Interrupt Flag bit
1 = System oscillator failed, clock input has changed to INTRC (must be cleared in software)
0 = System clock operating
Unimplemented: Read as â0â
USBIF: USB Interrupt Flag bit
1 = USB has requested an interrupt (must be cleared in software)
0 = No USB interrupt request
Unimplemented: Read as â0â
HLVDIF: High/Low-Voltage Detect Interrupt Flag bit
1 = A high/low-voltage condition occurred
0 = No high/low-voltage event has occurred
Unimplemented: Read as â0â
