Figure 16 Volume Update Using Zero Cross Detection
If there is a long period where no zero-crossing occurs, a timeout circuit in the WM8986 will
automatically update the volume. The volume updates will occur between one and two timeout
periods, depending on when the INPPGAVU bit is set as shown in Figure 17.
