Product data sheet
8.8 Address counter
8.9 Display data RAM
The Address Counter (AC) assigns addresses to the DDRAM and CGRAM for reading
and writing and is set by the commands ‘set DDRAM address’ and ‘set CGRAM address’.
After a read/write operation the address counter is automatically incremented or
decremented by 1. The address counter contents are output to the bus (DB6 to DB0)
when bit RS = 0 and bit R/W = 1.
The Display Data RAM (DDRAM) stores up to 80 characters of display data represented
by 8-bit character codes. RAM locations which are not used for storing display data can be
used as general purpose RAM. The basic RAM to display addressing scheme is shown in
Figure

display mapping for right and left shift respectively.
When data is written to or read from the DDRAM, wrap-around occurs from the end of one
line to the start of the next line. When the display is shifted each line wraps around within
itself, independently of the others. Thus all lines are shifted and wrapped around together.
The address ranges and wrap-around operations for the various modes are shown in
