When D0 goes LOW, voltage follower turns off. When D0 goes
HIGH, it turns on.
When D1 goes LOW, voltage regulator turns off. When D1 goes
HIGH, it turns on.
When D2 goes LOW, voltage booster turns off. When D2 goes
HIGH, it turns on.
Cancels Read-Modify-Write mode and returns column address to the original address (when Read-Modify-Write was issued).
Resets the Initial Display Line register, Column Address coun-
ter, Page Address register, register data of serial interface, and
Electronic Control register to their initial status. The Reset
command does not affect on the contents of display RAM.
Refer to the Reset circuit section of FUNCTIONAL DESCRIP-
TION.
The Reset command cannot initialize LCD power supply. Only
RES (that sets SR1 and SR2 to low) can initialize the supplies.
Selects one of eight power circuit functions using 3-bit register.
An external power supply and part of on-chip power supply
functions can be used simultaneously. Refer to Power Circuit
section of FUNCTIONAL DESCRIPTION for details.
Adjusts the contrast of LCD panel display by changing V
drive voltage that is output by voltage regulator of on-chip
power supply.
This command selects one of 32 V
storing data in 5-bit register. The V
should be determined depending on the external resistance.
Refer to the Voltage Regulator Circuit section of FUNC-
TIONAL DESCRIPTION for details.
This command is valid only when voltage regulator circuit is
turned on by Set Power Control command.

Clock outputs when D is low, but clock stops when D is high.
Set register to (D4,D3,D2,D1,D0)=(0,0,0,0,0) to suppress elec-
tronic control function.
Stops clock output at CL to reduce current consumption.
Sets LCD panel in power save mode if Static Drive ON is issued
when the display is off. Power consumption drops power
consumption level.
When LCD panel enters Power Save mode:
(a) Both oscillator and power supply stop.
(b) LCD driver stops, and segment and common driver have
(c) External clock input is disabled, and clock output is set
(d) Both display data and operation mode before issue of
(e) All LCD driver voltages are fixed to V
The Power Save is released when the display is turned on or
when Static Drive OFF is issued. If external voltage driver
resistors are used to supply voltage to LCD panel, current
passing through resistors must be cut off. An external power
supply must be turned off if used; its voltage must be fixed to
floating or V
* When the S1D15206 series is operating, the internal status

data set by commands is held. However, the internal status
may change due to an excessive ambient noise. The package
and system noise generation must be suppressed or a noise
protection design must be considered.
We recommend to periodically refresh the internal status
data to prevent a spike noise and other interference.

(As the power control register is cleared, the Set Power
Control command must be issued again after the Power
