Instruction Setup Examples
Initial setup
Note: As power is turned on, this IC outputs non-LCD-drive potentials V
2 – V6 from SEG terminal (generates output for driving the LCD)
and V
1 – V4 from COM terminal (also used for generating the LCD drive output). If charge remains on the smoothing capacitor being
inserted between the above LCD driving terminals, the display screen can be blacked out momentarily. In order to avoid this trouble,
it is recommended to employ the following powering on procedure.
• When the built-in power is used immediately after the main power is turned on:
Turn on VDD and VSS power while maintaining
RES terminal at LOW.
Wait until the power supply is stabilized.
Turn on the initial setup mode (Default). *1
Initial setup is complete
Function select through the commands (user setup).
LCD bias set *2
ADC select *3
Common output mode select *4
Function select through the command (user setup).
Electronic volume *5
Function select through the command (user setup)
Power control set *6
Cancel the reset mode (RES terminal = HIGH).
Operations ranging from powering on
through the power control set must be
completed within 5 ms.
* This duration of 5 ms depends on the panel characteristics as well as capacity of the capacitor concerned.
Notes: *1: Refer to the “Reset Circuit” in the Function Description.
*2: Refer to the “LCD Bias Set” in the Command Description (11).
*3: Refer to the “ADC Select” in the Command Description (8).
*4: Refer to the “Output State Register Set” in the Command Description (15)
*5: Refer to the “Supply Circuit” in the Function Description and the “Electronic Volume Register Set” in the Command Description
(17).
*6: Refer to the “Supply Circuit” in the Function Description and the “Power Control Set” in the Command Description (16).
