The hd44780 LCD the datasheet states that the
power supply conditions for correctly operating the internal reset circuit are not met, and initialization by
instructions becomes necessary. Could someone clarify this statement?

The LCD controller must be initialized every time on power on.
If a power loss is detected, i.e. even on a temporary drop in voltage (brownout), it must be initialized.

Mean that I need to put the initialization code in the void setup?
