3.1.2
Configuration register
The Configuration register is used to store the device settings such as Device Operation
mode, OS/INT Operation mode, OS/INT Polarity, and OS/INT 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
Table 6
). The entire register is volatile and
thus powers-up in its default state only.
