This is the most positive voltage supply pin of the chip.
A stabilization capacitor should be connected between
this pin and VSS when the converter is used. It must be
connected to external source when the converter is not
used.

This pin is Data/Command control pin. When the pin is
pulled high and serial interface mode is selected, the data
at SDIN is treated as data. When it is pulled low, the
data at SDIN will be transferred to the command register.
For detail relationship to MCU interface signals, please
refer to the Timing Characteristics Diagrams.
