Cursor or Display Shift
• Doesn't change the DDRAM content.
• Leaves AC in case of a screen shift.
• Moves and/or shifts the cursor to the right or left. The cursor goes to the second line
if it exceeds the 32nd position of the first line. It also goes to the first line when it
exceeds the 32nd position of the second line.
• During a screen shift the two lines only move horizontally, the first line never passes
to the second one.
Figure 28.34 describes how to choose the moving direction.

Set DDRAM Address
• Puts the address indicated by a6a5a4a3a2a1a0 into AC.
• When the number of lines is 2, the address goes from 00h to 1Fh for the first line, and
from 40h to 5Fh for the second line.
•The a6 bit indicates the line: a6=0 indicates the first line and a6=1 indicates the
second line.
Function Set
• If DL = 1, the data exchange is 8 bits wide.
• If N = 0, the display takes place on one line. If N = 1, the display takes place on two
lines.
