The module includes the Vacuum Fluorescent Display glass, VF
drivers and micro-controller ICs with refresh RAM, character
generator and interface logic. The high speed 8 bit parallel
interface is 5V TTL/CMOS compatible suitable for connection to
a host CPU bus. The asynchronous serial interface accepts
baud rates up to 38400, none parity. Three character font tables
can be software selected. User defined characters and many
control commands are available.
