[Note 1]: The upper left corner of the page is the character pattern 0-0, and from there to the right ~0-1, ~0-2, ~0-3,....
[Note 2]: The numbers on the page are the VRAM addresses (hexadecimal) of each character pattern name data, based on the VRAM address of the pattern name data of character patterns 0-0.

Pattern name data size: 2 words

Character pattern size: 1 cell horizontal x 1 cell vertical
