SCROLLING GRAPHIC DISPLAY
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.

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.
