CONT U/D (Contrast Up Down)
[1, 0, 0, X, 0, 0, 1, 1/0]
This command selects the voltage of VSS2, 3 that is used as the reference voltage for the LCD
bias. When the value of VSS2, 3 is changed, the contrast is changed accordingly.
The contrast is controlled by the value of the 3-bit up/down counter so that eight stages are
supported. The value of the up/down counter is incremented when "1" is entered by this
command and decremented when "0" is entered. The counter changes within the range of 0
to 7.
When the counter reaches 7, it goes back to "0".
According to the settings of N1 and N2, the contrast stages can be changed to 1 to 8, 2 to 9, or
3 to A.
At stage 0, the bias voltage is minimized. The larger the contrast stage, the higher the bias
voltage. At stage A, the bias voltage is maximized.
After a low RESET is input, the counter is set to the minimum value specified by N1 and N2.
Example: 67012345670
Note: At some contrast stages, the bias voltage may be increased to 5.5 V or higher. Adjust
the stage so that the bias voltage does not exceed 5.5 V.
STOP (Set Stop Mode)
[1, 0, 0, X, 0, 1, 0, 0]
This command sets standby mode. Specifically, the command stops the oscillation block to
prevent current form flowing through the oscillation block and outputs the VDD level to all
LCD output pins. Standby mode is canceled when D0 is set to "1" regardless of the setting of
the C/D pin. When a command or data with D0 set to "1" is entered, the command is executed
or the data is input. At the same time, standby mode is canceled.
After RESET = "L", standby mode is disabled.
SOE/D (Serial Out Enable/Disable)
[1, 0, 0, X, 0, 1, 1, 1/0]
This command controls the impedance of the SO output pin. The command is valid only when
the serial interface is used. When D0 is set to "0", the SO pin is set in the high impedance state.
After RESET = "L", D0 is set to "0".
DISP (Display On/Off)
[1, 0, 0, 1/0, 1, 0, 0, 1/0]
This command sets LCD display mode. When D0 is set to "1", the LCD is turned on. When
D0 is set to "0", the LCD is turned off, in which case, the VDD level is output to all segment and
common pins. When the LCD is turned ON (D0="1"), and D4 is set to "1", only arbitrators are
displayed and when D4 is set to "0", both characters and arbitrators are displayed. The table
below lists display modes.
After RESET = "L", both D4 and D0 are set to "0".
