Zero cross circuit timer
If a zero cross is not detected during the period from the
completion of the data transfer to the point the timer
overflows, the control data is enabled forcibly.

× VDD voltage generator used for analog ground
A capacitor of several ten F must be connected between
VREF and VSS to minimize power supply ripple.

Chip enable
Data is written to the internal latch when this pin goes from
high to low. The analog switches operate at that time. Data
transfer is enabled when CE is high.
