Display Data Byte
The supplied byte must be a valid ASCII representation of a character as shown in
Figure C-9.
The character set is stored in block RAM (used as ROM). The CharacterSet.xls file
contains the layout of the block RAM character set. The block RAM (see Figure C-10) is
organized as small arrays of eight bytes, which is easy for address calculation.
