GENERAL DESCRIPTION
The MSC7128-xx is a general purpose display controller for vacuum fluorescent display tube.
The MSC7128-xx drives displays with up to 35 anodes (dots) and up to 16 grids (characters) plus
a cursor.
The controller accepts command and display data input words on a clocked serial input line.
Commands control the on/off duty cycle, starting character position, number of characters to
display and display modes (PLA mode and Lamp Test mode). An internal PLA-type character
generator provides character decoding and dot pattern generation for the full 128 characters.
