Display Data Byte

The supplied byte must be a valid ASCII representation of a character as shown in

Figure C-9.

UG199_C_09_050106

Figure C-9:ASCII Character Representations

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.
