OSCFIF — USBIF — —HLVDIF — —

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 = System oscillator failed, clock input has changed to INTRC (must be cleared in software)

0 = System clock operating

bit 6 Unimplemented: Read as ‘0’

bit 5 USBIF: USB Interrupt Flag bit

1 = USB has requested an interrupt (must be cleared in software)

0 = No USB interrupt request

bit 4-3 Unimplemented: Read as ‘0’

bit 2 HLVDIF: High/Low-Voltage Detect Interrupt Flag bit

1 = A high/low-voltage condition occurred

0 = No high/low-voltage event has occurred

bit 1-0 Unimplemented: Read as ‘0’
