7. COMMAND
Table 4 lists the commands. S1D12200 Series identifies
the data bus signal using different combinations of A0
and WR (E). High speed command interpretation and
execution are possible since only the internal timing is
used.
• Command Overview
Instruction execution duration of dependents on the
internal process time of S1D12200 Series, therefore it is
neces-sary to provide a duration larger than the system
cycle time (t
in-struction.

This command presets the address counter to 30H
and moves the cursor, when it is present, to the first
digit of the first line.
This command performs on or off of display and

The cursor position indicates the position of address
counter.
Therefore, whenever moving the cursor, change
the address counter value using the RAM address
set command or the auto increment done by writing
the RAM data.
ISelective flashing symbol display is possible by
selecting (C, B) = (1, 0) and thus locating the
address counter to the position of the symbol register
through selecting (since the symbol is corresponding
to the character at each 5 dots).
This command is used to controlling the oscillation
circuit and setting or resetting the sleep mode.
