HD66710

• 4-line display (NW = 1)

 Case 1: The first line is displayed from COM1 to COM8, the second line is displayed from COM9

to COM16, the third line is displayed from COM17 to COM24, and the fourth line is displayed

from COM25 to COM32. Care is required because the DDRAM addresses of each line are not

consecutive. For example, the case is shown in Figure 6 where 8 × 4-line display is performed

using the HD66710.

When a display shift operation is performed, the DDRAM address shifts. See Figure 6.
