On the other hand, when using the reset command, only
the items 11 to 20 of the above-mentioned initial setting
are executed.
When the power is turned on, the initialization using the
RES pin is required. After the initialization using the
RES pin, each input pin needs to be controlled normally.
Besides, when the MPU control signal has high
impedance, overcurrent may be applied to an IC. After
turning on the power, take action so that the input pin
cannot have high impedance.
The S1D15705 Series discharge electric charges of V
and V
power supplies for driving LCD are used, do not input
