Instructions Affecting Custom Characters
The module allows the user to define 8 unique special characters. The pattern of the characters is stored in the
CG RAM. The relationship between the CG RAM address and the character pattern is illustrated in Figure 4.
The Read Data from CG RAM, Write Data to CG RAM, and Set DD RAM instructions provide for easy
programmability.
