When D is low, the right rotation (normal direction). When
D is HIGH, the left rotation (reverse direction).
When D goes LOW, the static drive turns off. When D goes
HIGH, the static drive turns on.
Forcibly turns the entire display ON and makes all common
outputs selectable regardless of RAM data contents. The RAM
data is held.
The LCD panel enters Power Save mode if Static Drive ON
command is issued when the display is off. Refer to the Power
Save section for details.
Selects the LCD driver duty. However, the bias of LCD driver
voltage is fixed when on-chip power circuit is used (refer to
Subsection).
Increments the duty by 1. If 1/8 duty is set for the S1D15206,
for example, it is incremented to 1/9 duty. If 1/16 duty is set, it
is incremented to 1/17 duty. The COMS terminal functions as
COM8 or COM16. The display line of RAM area correspond-
ing to page address 4, or D0, is always accessed.

A pair of Read-Modify-Write and End commands must always
be used. Once Read-Modify-Write is issued, column address is
not incremented by Read Display Data command but
incremented by Write Display Data command only. It contin-
ues until End command is issued. When the End is issued,
column address returns to the address when Read-Modify-
Write was issued. This can reduce the microprocessor load
when data of a specific display area is repeatedly changed
during cursor blinking or others.
