Table 22 Left and Right Output Mixer Mute and Volume Control
The mono output mixer can output, left, right, left+right or a buffered VMID. 0dB or 6dB attenuation is
selectable using MOUTVOL register bit. It is recommended to attenuate a mono mix of left and right
channels by 6dB in order to prevent clipping. This attenuation control (MOUTVOL) should not be
modified while OUT3 is enabled as this may cause an audible click noise.
