<Setting example: S1D15705
Set the value of the electronic control register as the
intermediate value (D5, D4, D3, D2, D1, D0) =
(1,0,0,0,0,0). From the foregoing we can establish the
expression:

In the use of the above-mentioned external resistor,
the liquid crystal power supply voltage V
be set by adding the resistors to finely adjust Ra’
and Rb’. Also in this case, the liquid crystal power
