This register defines the format of the temperature data in the readout register. The LM95010 only supports one format as defined by the values of this register.

BitTypeDescription
2-0RResolution. This field defines the value of 1 LSb of the Temperature Readout field in the Readout Register. The SensorPath specification defines many different weights for the temperature LSb. The LM95010 supports a resolution of 0.25 °C and thus a value of 010 for this field. For a full definition of this field please refer to the SensorPath specification.
5-3RNumber of Bits. This field defines the total number of significant bits of the Temperature Readout field in the Readout register. The total number of osignificant bits includes the number of bits representing the interger part of the temperature data and the fractional part of it, as defined by the Resolution field. The LM95010 supports 10 bits and thus a value of 001 for this field. For a full definition of this field please refer to the SensorPath specification.
6RSign (Signed Data). Defines the type of data in the Temperature Readout field of the Readout register.

0: Unsigned, positive fixed point value.


1: Signed, 2's complement fixed point value. (value for the LM95010)

7RRoutSize (Readout Register size). Defines the total size of the Readout register.

0: 16 bits. (LM95010 default)


1: 24 bits.

8R/WIntSens (Internal Sensor Support). Indicates if the device supports internal temperature measurements, as the LM95010 does.

0: No internal temperature measurement


1: Internal temperature sensor implemented. (value for the LM95010)

15-9ROReserved. Will always read "0".
