VDD
Connect a capacitor of a few tens of F between Vref and AVSS
(VSS) as a VDD/2 voltage generator, current ripple
countermeasure.

External muting control pin
Setting this pin to VSS level sets forcibly fader volume block to
∞ level.

VDD
Timer pin when there is no signal in the zero-cross circuit.
Forcibly set data when there is no zero-cross signal, from the time
the data is set until the timer ends.

VDD
Chip enable pin. Data is written to the internal latch and the analog
switches are operated when the level changes from High to Low.
Data transfer is enabled when the level is High.
