Low Rate Function
This function is not supported by the LM40 and therefore this field is read only.

R/W
ATE (Attention Enable). When set, this bit enables an Attention Request signal to be generated by the
LM40, 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
6
R/W
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

R/W
EN1-EN4 (Enable Sensor 1-4). Same as EN0 for Voltage sensors 1-4.
