However, serial data can be transferred when the INH pin is low.
VLCD0
90
LCD drive 4/4 bias voltage (high level) supply pin. The level on this pin can be
changed by the display contrast adjustment circuit.
However, (VLCD0 - VLCD4) must be greater than or equal to 4.5V.

Also, external power must not be applied to this pin since the pin circuit includes the
display contrast adjustment circuit.
