Low-Power, Multifunction, Polyphase AFE
with Harmonics and Tamper Detect
* These registers represent the algebraic sum of the positive and reverse energy in the two “raw” registers noted. Thus, the energy
accumulated in these virtual registers represents the net energy.
To avoid significant conversion loss, ENR_LSB should be chosen such that ENR_CC is > 1000. Calculate the value
of ENR_CC according to the following formula:
This register contains the temperature conversion coefficient that is applied to convert the temperature sensor bina-
ry output into degrees Celsius, per the following equation, where RAW_TEMP is the raw temperature sensor output.
Note that TEMP_CC should be obtained by calibrating the temperature sensor at the desired operation condition.
Typical approximate value is TEMP_CC = 0x0426. To read temperature, use the special register command 0xC01.
