Bit Field Type Reset Description
7 0 W 0h Must write 0.
6 EN TEMP SENS CONV R/W 0h This bit enables the temperature-to-digital conversion process of temperature sensor. This bit can be set to '1' after temperature sensor is enabled by setting EN TEMP SENSE bit to '1'.
5 EN TEMP SENSE R/W 0h This bit enables temperature sensor present inside device
4-3 0 W 0h Must write 0.
2 EN TEMP DATA READOUT R/W 0h This bit places the 9-bit digital equivalent of temperature on register bits TEMPDATA[8:0].
1-0 0 W 0h Must write 0.
