Description
Low Rate Function
ATE (Attention Enable).
When set, this bit enables an Attention Request signal to be generated by the
LM41, if one or more EN0-EN4 bits of this register are set.
0: Attention Request disabled (from enabled Temperature Sensor- default)
1: Attention Request enabled
EN0 (Enable Sensor 0).
When this bit is set, the Voltage Sensor 0 is enabled for voltage measurements.
0: Voltage Sensor disabled (default)
1: Voltage Sensor enabled
EN1-EN4 (Enable Sensor 1-4).
Same as EN0 for Voltage sensors 1-4.
0: Voltage Sensor disabled (default)
1: Voltage Sensor enabled
Reserved.
Will always read "0".
This function is not supported by the LM41 and therefore this field is read only.
