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.
