Register pointers selection summary
Configuration register
The configuration register is used to store the device settings such as device operation
mode, OS operation mode, OS polarity, and OS fault queue.
The configuration register allows the user to program various options such as thermostat
fault tolerance, thermostat polarity, thermostat operating mode, and shutdown mode. The
user has READ/WRITE access to all of the bits in the configuration register except the MSB
(Bit7), which is reserved as a “Read only” bit (see
thus powers-up in its default state only.
