Display RAM
The display RAM contains 80
× 8 bits (80 bytes). Each byte contains 7 character dots generated by
the character generator or by software and one single bit for cursor representation or special
segments.
The bytes of the display RAM are addressed by the contents of register LCDADR.
The valid addresses are from 00H to 4FH, where locations 2DH to 4FH are unused in 8-line
operation mode.
