- RAM Structure

The static display RAM is organized into 1024

´4 bits and stores the display data. The contents of the RAM are directly

mapped to the contents of the LCD driver. Data in the RAM can be accessed by the READ, WRITE and

READ-MODIFY-WRITE commands. The following is a mapping from the RAM to the LCD patterns.
