Description
ATE (Attention Enable).
When set, this bit enables an Attention Request signal to be generated by the
LM32, if the EN0, EN1 or EN2 bits of this register are set.
0: Attention Request disabled (from enabled Temperature Sensor- default)
1: Attention Request enabled (from enabled Temperature Sensor)
EN0 (Enable Sensor 0).
When this bit is set, the Local Temperature Sensor is enabled for temperature
measurements.
0: Temperature Sensor disabled (default)
1: Temperature Sensor enabled
EN1 (Enable Sensor 1).
When this bit is set, the Remote Thermal Diode 1 Temperature Sensor is enabled
for temperature measurements.
0: Temperature Sensor disabled (default)
1: Temperature Sensor enabled
EN2 (Enable Sensor 2).
When this bit is set, the Remote Thermal Diode 2 Temperature Sensor is enabled
for temperature measurements.
