I was plannung to use a K10 on a project, but for lack of stock i am a K40 for the prototype... i won't need the LCD, so the chargepump got no use to me... can i leave the VLLx and VCAPx pins unconnected (with the chargepump turned off). 

 

I won't be using the RTC either... can i leave the Vbat pin unconnected either.. or should i supply 3v3 on that?

 

Thank yoiu!!
