7. COMMAND DESCRIPTION
S1D15715 Series identifies the data bus signal by a combination of A0,
Interpretation and execution of commands are performed only by the internal timing independent of external
clocks.
In the 80-series MPU interface, the command is activated when a LOW pulse is input to
and when a LOW pulse in input to
In the 68-series MPU interface, the S1D15715 series enters a read mode when a HIGH level is input to R/W pin
and a write mode when a LOW level is input to R/
input to E pin.
Therefore, in the command description and command table, the 68-series MPU interface is different from the
80-series MPU interface in that
Taking the 80-series MPU interface as an example, commands will be explained below.
When the serial interface is selected, the data is input in sequence starting with D7.
7.1 Display ON/OFF
This command turns the display ON and OFF.
When the display OFF command is executed when in the Display all points ON mode, Power saver mode is
entered. See the section on the Power saver for details.
7.2 Display normal/reverse
This command can reverse the lit and unlit display without overwriting the contents of the DDRAM.
The contents of the DDRAM will be maintained.
7.3 Display all points ON/OFF
This command makes it possible to force all display points ON regardless of the content of the DDRAM.
Even when this is done, the DDRAM contents are maintained.
This command takes priority over the display normal/reverse command.
When the display all points ON command is executed when in the Display OFF mode, Power saver mode is
entered.
See the section on the Power saver for details.
