1. FEATURE
This vacuum fluorescent display (VFD) module consists of a 20 character by 2 line 5×8 dot
matrix display, DC-DC/AC converter, and controller/driver circuitry.
The module can be configured for a Motorola M68-type parallel interface, an Intel I80-type
parallel interface, or a synchronous serial interface.
A character generator ROM with 240 5×8 characters is provided along with RAM for the user
to program an additional 8 characters. The luminance level of the VFD can be varied by
setting two bits in the function set instruction.
Two hundred and forty character fonts consisting of a alphabets, numerals and other symbols
can be displayed.
This module has a dual-port RAM that allows data and instructions to be the module
continuously. Thus, the busy flag is always 0 and the host never has to read the busy flag bit to
determine if the module is busy.
Due to this feature, the execution times for each instruction are not specified.
