Reads 8-bit data from display RAM area specified by column
address and page address. As the column address is incremented
by 1 automatically after each write, the microprocessor can
continue to read data of multiple words. A single dummy read
is required immediately after column address setup. Refer to
the display RAM section of FUNCTIONAL DESCRIPTION
for details. Note that no display data can be read via the serial
interface.
Changes the relationship between RAM column address and
segment driver. The order of segment driver output pins can be
reversed by software. This allows flexible IC layout during
LCD module assembly. For details, refer to the column address
section of Figure 4. When display data is written or read, the
column address is incremented by 1 as shown in Figure 4.
When D is low, the right rotation (normal direction). When D
is high, the left rotation (reverse direction).
Reverses the Display ON/OFF status without rewriting the
contents of the display data RAM.
When D is low, the RAM data is high, being LCD ON potential
(normal display).
When D is high, the RAM data is low, being LCD ON potential
(reverse display).
Forcibly turns the entire display on regardless of the contents of
the display data RAM. At this time, the contents of the display
data RAM are held.
This command has priority over the Normal/Reverse Display
command. When D is low, the normal display status is pro-
vided.
When D is high, the entire display ON status is provided.
If the Entire Display ON command is executed in the display
OFF status, the LCD panel enters Power Save mode. Refer to
the Power Save section for details.
Selects a bias ratio of the voltage required for driving the LCD.
This command is enabled when the voltage follower in the
power supply circuit operates.
(The LCD bias setting command is invalid for the S1D15303
and S1D15304. They are being fixed to the 1/5 bias.)

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.
