2.3 VCC - Horizontal Logic Power Supply
The power supply for the horizontal logic circuitry must be set at 3.3V. The panel must be
ready for use before this supply is turned on. A general purpose output pin may be used to
control VCC (GPO on the S1D13706). Figure 2-4: “VCC Power Supply” shows an
example of this power supply. The control signal (GPO) in this implementation activates
VCC when it is low.
