CHAPTER 7 EXTERNALS/AUXILIARY MECHANISMS

2. LCD Processing

The microprocessor on the DC controller PCB sends commands to the LCD
controller according to instructions from its programs. In response, the LCD controller
interprets and executes the commands. The LCD controller also turns on and off various
instructions according to programs.
The LCD controller also serves to write display text codes into display RAM as
necessary; the display RAM data is then sent to the display panel in response to the
timing signals generated by the LCD controller.
