Operation
Shift cursor to the left, AC is decreased by 1
Shift cursor to the right, AC is increased by 1
Shift all the display to the left, cursor moves according to the display
Shift all the display to the right, cursor moves according to the display

DL : Interface Data Length Control Bit
When DL = "High", it means 8-bit bus mode with MPU.
When DL = "Low", it means 4-bit bus mode with MPU. So to speak, DL is a signal to select 8-bit or 4-bit bus
mode. When 4-bit bus mode, it needs to transfer 4-bit data by two times.
N : Display Line Number Control Bit
When N = "Low", it means 1-line display mode.
When N = "High", 2-line display mode is set.
F : Display Font Type Control Bit
When F = "Low", it means 5
×
8 dots format display mode
When F = "High", 5

11 dots format display mode.

Set DDRAM address to AC. This instruction makes DDRAM data available from MPU. When 1-line display mode
(N = 0), DDRAM address is from "00H" to "4FH". In 2-line display mode (N = 1), DDRAM address in the 1st line is
from "00H" to "27H", and DDRAM address in the 2nd line is from "40H" to "67H".

This instruction shows whether S6A0069 is in internal operation or not. If the resultant BF is High, it means the
internal operation is in progress and you have to wait until BF to be Low, and then the next instruction can be
performed. In this instruction you can read also the value of address counter.
