Configuration Register

The configuration register allows the user to program various DS75LX options such as conversion resolution,

thermostat fault tolerance, thermostat polarity, thermostat operating mode, and shutdown mode. The configuration

has read/write access to all bits in the configuration register except the MSb, which is a reserved read-only bit. The

entire register is volatile, and thus powers up in its default state.
