supply determined by the liquid crystal cell are impedance-converted by
resistive divider and operational amplifier for application.
The following order must be maintained:
V3 ≥ V2 ≥ V1 ≥ VC ≥ MV1 ≥ MV2 ≥ MV3 (=VSS)
Master operation: When power supply is turned on, the following
voltage is applied to each pin by the built-in power supply circuit.
MV3 is connected to with VSS inside the IC chip.
