Command Description
Table 3 is the command table. The S1D15200 series identifies a data bus using a combination of A0 and R/W (RD or WR)
signals. As the MPU translates a command in the internal timing only (independent from the external clock), its speed
is very high. The busy check is usually not required.
(1) Display ON/OFF
This command turns the display on and off.
• D=1: Display ON
• D=0: Display OFF
(2) Display Start Line
This command specifies the line address shown in Figure 3 and indicates the display line that corresponds to COM0. The
display area begins at the specified line address and continues in the line address increment direction. This area having
the number of lines of the specified display duty is displayed. If the line address is changed dynamically by this command,
the vertical smooth scrolling and paging can be used.
This command loads the display start line register.
See Figure 2.
(3) Set Page Address
This command specifies the page address that corresponds to the low address of the display data RAM when it is accessed
by the MPU. Any bit of the display data RAM can be accessed when its page address and column address are specified.
The display status is not changed even when the page address is changed.
This command loads the page address register.
See Figure 2.
