Notes: *22. Add a capacitor to the logic block power supply line so that the logic block power supply voltage VDD rise time when power is applied and the

logic block power supply voltage VDD fall time when power drops are both at least 1 ms, as the LC75817NE/NW is reset by the VDET.

*23. If a variable resistor is not used for display contrast fine adjustment, the VLCD4 pin must be connected to ground.

*24. If the function of INH pin is not used, the INH pin must be connected to the logic block power supply VDD.

*25. The DO pin, being an open-drain output, requires a pull-up resistor. Select a resistance (between 1 to 10 kΩ) appropriate for the capacitance of

the external wiring so that signal waveforms are not degraded.
