? When fewer than 45 segments are used, only 56-bits of serial data need to be sent. However, the display data
D1 to D44 and the control data must be sent.

Note) Sn (n=1 to 4): Segment output port
Pn (n=1 to 4): General-purpose output port
The following shows the correspondence between output pins and display data when the general-purpose output port
is selected.

For example, if output pin S4/P4 is for the general-purpose output port, output pin S4/P4 outputs high and low-level
when display data D13=“1” and D13= “0”, respectively.
(2) DR ????? 1/2 bias drive, 1/3 bias driver switching control data
This control data switching LCD 1/2 bias driver and 1/3 bias driver.
