Figure 4. O.S. OUTPUT Operation Example
CONFIGURATION REGISTER
The configuration register allows the user to program various DS75LV options such as conversion resolution,
thermostat fault tolerance, thermostat polarity, thermostat operating mode, and shutdown mode. The configuration
register is arranged as shown in Figure 5 and detailed descriptions of each bit are provided in Table 4. The user
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.
