Input Data
The serial port is required the 16 bits data (D0 to D15). When the data length is less than 16 bits, the
internal register will not be up dated. And when the data length is more than 16 bits, this register will take
later 16 bits and ignore the faster bit.

1. When +5 V or +3.3 V power supply goes to Low, then POR = Low.
Note: When POR = Low, internal RESET signal becomes High and when RESET = High,
POR output is able to construct the wired logic with external signal.
