• Volume Setting
In zero crossing mode (ZCEN=H), the volume value is changed when one zero crossing is detected after
the rise of CSN. The volume value is changed also when no zero crossing is detected for 20 ms. In normal
mode (ZCEN=L), zero crossing detection is not performed and volume value is changed immediately
after the rise of CSN.
The input codes and volumes values are related as described in the following table.
