The character map follows the Arial font for 96 charac-
ters in the x0100000 through x1111111 range. The first
32 characters map the 24 user-definable positions
(RAM00 to RAM23), plus eight extra common charac-
ters in ROM.
User-Defined Fonts
The 24 user-definable characters are represented by
48 entries of 7-bit data, two entries per character, and
are stored in the MAX6850’s internal RAM.
