Character Tables and Codes
Data is written to the display one byte at a time. If the byte received is
greater than 1Fh it is considered as 5x8 dot matrix character data. This
character is written to the current cursor position and the cursor
position is then incremented by one. When data is written to the last
character position of the top line the cursor position moves to the first
position of the bottom line. When data is written to the last character
position of the bottom line the cursor position moves to the first
position of the top line.
