When presenting byte value 30 hex, character 0 must be displayed. Shifting the value
00110000b (30h) up three positions gives the value 180h or 348d.
Because each character uses eight byte locations, character 0 in the character set starts from
memory location 348 decimal.
For example, character X has byte value 58h or 01011000b. Shifting this value three
positions gives the value 2C0h or 704d.

data is latched and then shifted left three positions. This shifted value is the start byte for a
counter that outputs an address to the block RAM. The result is a stream of bytes
representing a character for the display.
A small second counter determines when a new character is loaded into the block RAM
address counter.

The RAM array is divided in
pages of eight bytes by 16,
forming an array of 128 bytes.
This array represents one
column of standard ASCII table.
A character is stored as:
