Reset
When power is turned ON, the S1D15600/601/602 series
is initialized on the rising edge of RES. Initial settings are
as follows.
RES should be connected to the microprocessor reset
terminal so that both devices are reset at the same time.
RES must be LOW for at least 1 s to correctly reset the
S1D15600/601/602 series. Normal operation starts 1 s
after the rising edge on RES.

EPSON
If the built-in LCD power circuit of the S1D1560
is not used, the RES signal must be low when the external
LCD power supply is turned on. When the RES goes low,
each register is cleared to the above listed initial status.
However, the oscillation circuit and output pins (OSC2,
FR, SYNC, CLD, DYO, D0 to D7 pins) are not affected.
If the S1D15600 is not properly initialized when power
is turned ON, it can lock itself into a state that cannot be
cancelled.
Although S1D15600/601/602 Series devices maintain
the operation status under commands, when external
noise of excessive levels enters, their internal statys may
be changed. Consequently, it is necessary to provide
means to suppress noise occurring from package or the
system or orovide means to avoid influence of such
noise.
Also, to cope with sudden noise, we suggest you to set up
the software so the operation status can be periodically
refreshed.
When the Reset command is used, only initial settings 9
to 14 are active.
