3. Output pin states during the reset period
X: don’t care
Note:
*
5.These output pins are forcibly set to the segment output function and held low.
*
6.When power is first applied, these output pins are undefined until the S0 and S1 control data bits have been transferred.
*
7.Since this output pin is an open-drain output, a pull-up resistor of between 1 and 10 k
is required. This pin remains high during the reset period
even if a key data read operation is performed.

8.
Add a capacitor to the logic block power supply line so that the logic block power supply voltage V
DD
rise time when power is applied and the
logic block power supply voltage V
DD
fall time when power drops are both at least 1 ms, as the LC75863E/W is reset by the VDET.
The DO pin, being an open-drain output, requires a pull-up resistor. Select a resistance (between 1 to 10 k
) appropriate for the capacitance of
the external wiring so that signal waveforms are not degraded.
