DESCRIPTION
This bit always reads 0.
This bit reads at 1 when any of the SCV, SCG, or OC faults are active. Default value
is 0.
These bits contain the signed 12-bit value of the reference junction temperature.
This bit always reads 0.
This bit is a 1 when the thermocouple is short-circuited to V CC . Default value is 0.
This bit is a 1 when the thermocouple is short-circuited to GND. Default value is 0.
This bit is a 1 when the thermocouple is open (no connections). Default value is 0.
