When the on-chip oscillator is used, this input must be connected
to VDD1. An external clock signal, if used, is connected to this input. If
the oscillator and external clock are both inhibited by connecting the
OSC pin to VSS the display is not clocked and may be left in a DC state.
To avoid this, the chip should always be put into Power Down Mode
before stopping the clock.
Digital ground: must be connected with VSS2
Analog ground: must be connected with VSS1
