7. COMMAND
Table 4 lists the supported commands. The S1D12205
Series identifies a data bus by a combination of A0, WR
and E signals. It features HIGH-speed processing as the
• Command outline
As the execution time of each instruction depends on the
internal processing time of the S1D12205 Series, an
enough time greater than the system cycle time (
must be assigned for continuous instruction execution.
• Explanation of commands
During blinking, the cursor character is alternately
displayed normally and reversely. The normal and
reverse display is repeated approximately every one
second.

The following provides the relationship between the C
and B registers and cursor display.
The cursor display position is indicated by the address
counter. Accordingly, to move the cursor, change the
address counter value by automatic increment by writing
the RAM address set command or RAM data.
