VOLUME CONTROL
Figure 10 Volume Control
The Volume Control panel is used to control both analogue and digital volume settings of the
WM8973. The volume sliders update in ‘real’ time (i.e. the ‘Volume Submit’ button does not
have to be pressed to update the output volume level) but will only have an effect on the
output if the Volume Update bits are set. Once changes are made to the Volume Update bits,
the ‘Volume Submit’ button must be left clicked for the change to take effect. Pressing the
‘Volume Submit’ button will cause the settings shown on this panel to be written to the
WM8973. A full device register write is not sent.
