or other circuit.
Note:

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.

Notes on transferring display data from the controller
The display data (D1 to 75) is transferred to the LC75863E/W in two operations. All of the display data should be
transferred within 30 ms to maintain the quality of the displayed image.
