7. COMMAND DESCRIPTION
The S1D15710 series identifies data bus signals according to the combinations of A0, RD(E), and WR(R/W). Since the
interpretation and execution of commands are performed only by the internal timing independently of external clocks,
the S1D15710 performs high-speed processing that does not require busy check normally.
The 80 series MPU interface starts commands by inputting low pulses to the RD pin at read and to the WR pin at write
operation. The 68 series MPU interface enters the read state when HIGH is input to the R/W pin. It enters the write state
when LOW is input to the same pin. It starts commands by inputting high pulses to the E pin (for the timing, see the
Timing Characteristics of Chapter 10). Therefore the 68 series MPU interface differs from the 80 series MPU interface
in that RD(E) is set to “1 (H)” at status read and display data read in the Command Description and Command Table.
The command description is given below by taking the 80 series MPU interface as an example.
When selecting the serial interface, enter sequential data from D
Command description
(1) Display ON/OFF
This command specifies display ON/OFF.
For display OFF, the segment and common drivers output the V
(2) Display Start Line Set
This command specifies the display start line address of the display data RAM shown in Figure 4. The display area is
displayed for 65 lines from the specified line address to the line address increment direction. When this command is
used to dynamically change the line address, the vertical smooth scroll and page change are enabled. For details, see
the Line address circuit of “Function Description”.
