5 ALRMOUT_PIN ALRMOUT_PIN.
The ALRMOUT status can be reflected on the ALRMOUT output pin. The request to
reflect the interrupt status on this pin (INT_PIN=1) overrides the ALRMOUT_PIN
request.
0: ALRMOUT not reflected on output pin. Output pin disabled if INT_PIN=0.
1: ALRMOUT reflected to output pin if INT_PIN=0. If INT_PIN=1, interrupt status
appears on the output pin and ALRMOUT is not available on an output pin.
4 CK3_BAD_PIN CK3_BAD_PIN.
The CK3_BAD status can be reflected on the C3B output pin.
0: C3B output pin tristated
1: C3B status reflected to output pin
3 CK2_BAD_PIN CK2_BAD_PIN.
The CK2_BAD status can be reflected on the C2B output pin.
0: C2B output pin tristated
1: C2B status reflected to output pin
2 CK1_BAD_PIN CK1_BAD_PIN.
The CK1_BAD status can be reflected on the C1B output pin.
0: C1B output pin tristated
1: C1B status reflected to output pin
1
LOL_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
0
INT_PIN INT_PIN.
Reflects the interrupt status on the INT output pin.
0: Interrupt status not displayed on INT output pin. If ALRMOUT_PIN = 0, output pin is
tristated.
1: Interrupt status reflected to output pin. ALRMOUT_PIN ignored.
