The relationships between Character Generator RAM Addresses, Character Generator RAM Data (character patterns), and Character
Codes are depicted as follows:
1. 5 x 8 dot character patterns
Note1:
Note2:
Note3:
When all of the bit4-7 of the character code are 0, CG RAM character patterns are selected.
Note4:
" 1 ": Selected , " 0 " : No selected , " X " : Do not care (0 or 1).
Note5:
For example (1), set character code (b2 = b1 = b0 = 0, b3 = 0 or 1, b7-
b4 = 0) to display “ T ”.
That means character code (00) 16,and (08) 16 can
display “ T ” character.
Note6:
The bits 0-2 of the character code RAM is the character pattern line position. The 8th line is the cursor position and display is formed by logical OR
with the cursor.
It means that the bit0~2 of the character code correspond to the bit3~5 of the CG RAM address.
These areas are not used for display, but can be used for the general data RAM.
