The AM_AVC_MAX_GAIN property sets the maximum gain for automatic volume control. The maximum gain
value is given by MAXGAIN = g x 170 where g is the desired maximum AVC gain in dB. The CTS bit (and optional
interrupt) is set when it is safe to send the next command. This property may only be set or read in powerup mode.
