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

Table 7.
