2.4 DAC Volume Controls Tab
The “DAC Volume Controls” tab provides high-level control of all volume settings in the DAC of the
CS42L51. Status text detailing the CODEC’s specific configuration is shown in read-only edit boxes, in pa-
renthesis, or appears directly below the associated control. This text will change, depending on the setting
of the associated control. NOTE: Control groups that include “(SPE)” in its labeling are a part of the Signal

uration” tab. A description of each control group is outlined below (a description of each register is included
