Note: * 6. 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 1ms, as the LC75808W is reset by the VDET.
* 7. If a variable resistor is not used for display contrast fine adjustment, the VLCD4 pin must be connected to
ground.
* 8. If the function of the INH pin is not used, the INH pin must be connected to the logic block power supply
VDD.
* 9. The DO pin, being an open-drain output, requires a pull-up resistor. Select a resistance (between 1k Ω to
10k Ω ) appropriate for the capacitance of the external wiring so that signal waveforms are not degraded.
