Optional LCD power supply scheme
1. Option 1: LCD power supply is provided by a dedicated VLCD supply source, VSEL switch is open.
2. Option 2: LCD power supply is provided by the internal step-up converter, VSEL switch is closed, an
external capacitance is needed for correct behavior of this converter.
