Low-Power, Multifunction, Polyphase AFE
This signed register contains the linearity offset for phase X current channel when the programmable gain amplifier
is set to gain of 32 (that is, the measured current is below the low current threshold). The signed value represented
by this register is added to the current value. The total linearity compensation is applied as follows:
This register contains the result of the RMS calculation on the AUX channel. Usually, this is the neutral current chan-
nel, but can be defined to be the RMS average of any harmonic of the quantities defined in the AUX_MUX field of the
AUX_CFG register.
