POTENTIOMETER FEATURE REGISTER

Although the feature set of the DS2890 is primarily fixed, a mechanism to identify feature characteristics

of future 1-Wire potentiometers has been developed and implemented in the DS2890. As shown in

Figure 3, the feature register is an encoded read-only byte that describes the characteristics of the DS2890

and future 1-Wire potentiometers. Feature values that correspond to the DS2890 are highlighted. The

feature register is read with the READ CONTROL REGISTER potentiometer function command (see

“POTENTIOMETER FUNCTION COMMANDS”).
