I'm preparing an FMEA document where I need to know what actually happens if the LCDCAP pin does not get connected to ground... The datasheet says CAUTION every where this pin gets mentioned if not used, but no explanation. The only clue I have is that this is associated with a charge pump.
Is there any documentation on this? It seems to be fine when I test with it disconnected, but the word CAUTION scares me from an FMEA standpoint.
