Description

0R

ATE (Attention Enable). When set, this bit enables an Attention Request signal to generated by the

LM95010, if the EN0 bit is set.

0: Attention Request disabled (from enabled Temperature Sensor- default)

1: Attention Request enabled

1R

EN0 (Enable Sensor). When this bit is set, the Temperature Sensor is enabled for temperature

measurements.

The temperature conversion rate is controlled by this register as well as the Low Power Bit of Device Control Register. This

register is not defined by the SensorPath specification. Therefore, it must be accessed during BIOS run time. The conversion rate

is dependent on system physical requirements and limitations. The thermal response time of the MSOP package is one such

requirement.
