Status 1 Register (Diode Fault)

Status fault bits for open or shorted diode (that is,. Short Fault: D+ shorted to Ground or D-; Open Fault: D+ shorted to VDD, or floating). During fault conditions the temperature reading is 0 °C if unsigned value registers are read or –128.000 °C if signed value registers are read.
