Remark Plural terminal (VM) is not only 1 terminal and connect all terminals.
Notes 1. A standard voltage to use is chosen.
VREFsel: High level using external input VREF
VREFsel: Low level using internal reference voltage (VREF pin fixed GND level)
2. Input the video sync singnal to VD pin or VD pin. A free terminal is to do the following treatment.
When input VD: VD pin connect to VDD pin.
When input VD: VD pin connect to GND pin.
