7. COMMANDS
Table 4 shows a command list. In the S1D12300 Series,
each data bus signal is identified by a combination of A0
and WR (E).
Command interpretation and execution are performed by
only internal timing. This permits high-speed process-
ing.
• Outline of Commands
The execution time of each instruction is determined by
the internal processing time of the S1D12300 Series.
Accordingly, to execute instructions in succession, re-
serve a time exceeding the cycle time (t
the next instruction.

In the blink state, display characters in normal
video and display characters in monochrome re-
verse video are displayed alternately.
The repetition cycle of alternate display is about 1
second.
C
The relationship between C and B registers and
cursor display is shown in the following table.
The cursor display position corresponds to the
position indicated by address counter.
Accordingly, to move the cursor, change the ad-
dress counter value by the RAM Address Set
command or auto increment by writing RAM data.
If the address counter is set at the symbol register
position with (C, B) = (1, 0), symbols can be caused
to blink selectively.
