The voltage between pin 18 and GND (-5 to 0 volts) determines the contrast of the display.

The area selection determines the area (0 to 7) on which the data is written.

Pin 3 indicates whether the data lines (pins 5 to 12) contain an instruction (0) or represent the eight pixels of the current writing position (1).

Pin 14 has to be held on 0 volts in order to access the display.

After writing data, the current column is automatically incremented.
