On the other hand, when the reset command is used, the
above default settings from 11 to 19 are only executed.
When the power is turned on, the IC internal state
becomes unstable, and it is necessary to initialize it
using the RES terminal. After the initialization, each
input terminal should be controlled normally.
Moreover, when the control signal from the MPU is in
the high impedance, an overcurrent may flow to the IC.
After applying a current, it is necessary to take proper
measures to prevent the input terminal from getting into
the high impedance state.

While RES is LOW, the oscillator and the display
timing generator stop, and the CL, FR, FRS and DOF
terminals are fixed to HIGH. The terminals D0 to D7
are not affected. The V

resistor is connected between V
When the internal liquid crystal power supply circuit is
not used on other models of S1D15605 series, it is
necessary that RE is LOWwhen the external liquid
crystal power supply is turned on.
While RES is LOW, the oscillator works but the display
timing generator stops, and the CL, FR, FRS and DOF
terminals are fixed to HIGH. The terminals D0 to D7
are not affected.
