* 1: DE/SYNC mode select. Normally pull high.
When select DE mode, MODE=”1”, VS and HS must pull high.
When select SYNC mode, MODE= “0”, DE must be grounded.
* 2: Data shall be latched at the falling edge of DCLK.
* 3: Selection of scanning mode
Setting of scan control input Scanning direction

*4: Global reset pin. Active low to enter reset state. Suggest to connect with an RC reset circuit for stability. Normally pull high.
*5: Dithering function enable control, normally pull high.
When DITHB=”1”,Disable internal dithering function,
When DITHB=”0”,Enable internal dithering function,
