As seen in MPU Interface, the RES pin inputs data at the
same timing as MPU resetting and performs initialization
concurrently with the MPU. However, if this pin is put
into the high impedance for a certain period after the
MPU bus and ports are reset, perform a reset input after
the input to the S1D12400 series is definitively set.
For the reset signal, it is necessary to input ‘0’ level
pulses at least for 10 s as described in DC Characteristics.
The ordinary operation will be started in 1 s or more
after the rising edge of the RES signal. When the RES pin
becomes active, each register will be cleared and set to
the above setup status.
If initialization is not executed by the RES pin when the
supply voltage is applied, a clear disable status may
appear.
In case the built-in liquid crystal power circuit is not
used, the RES input must be active when the external
liquid crystal power supply is turned on.
