Instruction Setup: Reference (reference)
(1) Initialization
Note: With this IC, when the power is applied, LCD driving non-selective potentials V
and V
(COM pin) are output through the LCD driving output pins SEG and COM. When electric charge is

avoid occurrence of such a failure, we recommend the following flow when turning on the power.
When the built-in power is being used immediately after turning on the power:
