Notes:
*
22. 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 LC75817E/W is reset by the VDET.
*
23. If a variable resistor is not used for display contrast fine adjustment, the V
LCD
4 pin must be connected to ground.
*
24. If the INH pin is not used, it must be connected to the logic block power supply V
DD
.
*
25. 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.
