CK2_BAD_PIN.
The CK2_BAD status can be reflected on the LOS2 output pin.
0: LOS2 output pin tristated
1: CK2_BAD status reflected to output pin
CK1_BAD_PIN.
Either LOS1 or INT (see INT_PIN) status can be reflected on the INT_LOS1 output pin.
0: INT_LOS1 output pin tristated
1: LOS1 or INT (see INT_PIN) status reflected to output pin
LOL_PIN.
The LOL_INT status bit can be reflected on the LOL output pin.
0: LOL output pin tristated
1: LOL_INT status reflected to output pin
INT_PIN.
Reflects the interrupt status on the INT_LOS1 output pin.
0: Interrupt status not displayed on INT_LOS1 output pin. Instead, the INT_LOS1 pin
indicates when CKIN1 is bad. If CK1_BAD_PIN = 0, INT_LOS1 output pin is tristated.
1: Interrupt status reflected to output pin.
