The module includes the Vacuum Fluorescent Display
glass, driver and control ASIC, with integral refresh Graphic
RAM and logic for parallel and synchronous serial
interfaces. The high speed 8 bit parallel interface is 5V
CMOS compatible suitable for connection to a host CPU
bus. Brightness control and power down functions are
provided. A full data sheet is available.

The pattern in GRAM can be scrolled around the display. Horizontal scroll is achieved by
increment/decrement of the Display Start X Address. The vertical scroll process considers
layer 0, then layer 1 as a continuous 64 bit high vertical area within RAM.
