S1D15E06 Series
7. COMMAND
The S1D15E06 series identifies data bus signals by a combination of A0, RD(E) and WR(R/W). Interpretation and
execution of the command are executed by the internal timing alone which is independent of the external clock. This
allows high-speed processing.
The 80 series MPU interface allows the command to be started by entering the low pulse in the RD pin during reading
and by entering the low pulse in the WR pin during writing.
The 68 series MPU interface allows a read state to occur by entering HIGH in the R/W pin, and permits a write state
to occur by entering LOW. It also allows the command to be started by entering the high pulse in the pin E. (For timing,
see the description of “10. Timing characteristics”).
Accordingly, the 68 series MPU interface is different from 80 series MPU interface in that RD(E) is “1(H)” in the case
of display data/read shown in the Command Description and Command Table. The following describes the commands,
based on the example of the 80 series MPU interface:
When the serial interface is selected, enter data sequentially starting from D7.
Command Description
(1) Display ON/OFF
This command sets the display ON/OFF.
When display OFF is specified, segment and common drivers outputs the level selected by the display OFF Mode Select
command.

(2) Display OFF Mode Select
This command is used to set the output level of the segment and common driver when the display is off.
In the initial setting state, it becomes "D0 = 0".
* When D0 = 0 is selected in the case of S1D15E06D00B , the MV2 and common driver VSS level is output by segment
*
driver when display is off. Select D0 = 1 to use the S1D15E06D00B .

(3) Display Normal/Reverse
This command allows the display ON/OFF state to be reversed, without having to rewrite the contents of the display
data RAM. In this case, contents of the display data RAM are maintained.
