*1: Consideration must be given to the wait time until the internal generation V
DI
voltage is stabilized. The
wait time varies with external circuit, depending on the capacity between V
DI
and V
SS
. Therefore,
evaluate and set with sufficient margin.
Reference: When V
DD
= 5V and V
DI
stabilizing capacity at 4.7
µ
F, the wait time = 5 mS.
(The wait time is inversely proportional to the V
DD
voltage, but proportional to the V
DI
stabilizing capacity.)
*2: The contents of the display data RAM are undefined even in the state of initial setting following reset.
*3: Execute the OFF command when performing initial setting and refreshing even if it is set to non-use of
each function, so that a recovery can be made from a sudden change of internal state resulted from
excessive external noise.
Likewise, for the command used for setting the register value, reset the register when performing initial
setting and refreshing even if default values after reset are used as they are.
*4: LCD
voltages
(V
3
to MV
2)
are sure to supply all at the same timing.

*1 Reset the register when performing initial setting and refreshing even if it is set to use default values as
they are, so that a recovery can be made from a sudden change of internal state resulted from excessive
external noise.
*2 The contents of the display data RAM are undefined after completion of initial setting. Write data all the
display data RAMs to be used for display.
