STANDARD NAME:
7.4 CHARACTER GENERATOR RAM (CGRAM)
The CGRAM stores the pixel information (1 = pixel on, 0 = pixel off) for the eight user-
definable 5x8 characters. Valid CGRAM addresses are 00H to 3FH. CGRAM not being used to
define characters can be used as general purpose RAM (lower 5 bits only). Character codes 00H
to 07H (or 08H to 0FH) are assigned to the user-definable characters (see section 5.0 Character
Font Tables). The table below shows the relationship between the character codes, CGRAM
addresses, and CGRAM data for each user-definable character.
