The MAXQ3180 can monitor the RMS value of one auxiliary channel in addition to its normal processing. The
Auxiliary Channel Configuration register selects which input the auxiliary channel processes and what processing is
applied to the auxiliary channel.
This register contains the system clock frequency in kHz units. Because the default frequency is 8MHz, this register
defaults to 0x1F40.

Order of Harmonic (1–21). The output of harmonic voltage is read via virtual register 0x830 and current
at 0x840.
Enable Auxiliary Channel Harmonic Filter. When set, the auxiliary channel is processed through the
harmonic filter. The parameters for this filter can be set in the B0HARM and A1HARM registers.
Enable Auxiliary Channel. When set, enables auxiliary channel processing.
Auxiliary Channel Input Select. This three-bit field selects the input to be processed by the auxiliary
channel.
