The MAXQ3181 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.
