Cursor Shift
When display line mode is more than 1-Line, the cursor will move to the first position on the next line if AC reaches the last
valid address. If the line address is at the last line, the cursor will shift to the first position on the first line.
Screen Shift
The screen shift is performed simultaneously on each line in all kinds of display line mode. Each line is shifted individually.
The content kept in AC is not changed when performing Screen Shift operation.
Set CGRAM Address
This instruction sets CGRAM address into AC. This instruction makes CGRAM data available for MPU access.

Set ICON RAM Address
This instruction sets ICON RAM address into AC. This instruction makes ICON data available for MPU access. The valid
ICON RAM address is from "00H" to "0FH", when IS[1:0]=(0,1).
