ACTION
Lost the input status or no drive capability.
If both GPIO1 and GPIO0 are configured as the input or the same status for the output,
there is no effect. If they are configured as a different value as the output, it shows the
output of 0V and the part is reset.
Lost the input status or no drive capability.
If the GPIO0 is configured as input or the high status for the output, there is no effect. If it
is configured as low status for the output, the part is reset.
ALRTVDDL of the FMEA register is set to 1. ALRTFMEA of the STATUS register is set to 1.

No heartbeat.
The result is dependent on the circuit that drives the SHDN pin. If the circuit has strong
drive capability (ALRM
is OK as the VAA charged faster than the discharge so the part keeps in the normal
working mode.

The result is dependent on the circuit that drives the SHDN pin and AUXIN2.
The AIN2 register is around 0.
External temperature circuit lost the bias supply. So the AIN0 and AIN1 should be read as
close to 0V. Otherwise there is no effect.
The AIN1 register is close to full scale (0xFFF).
