1,VPP,Supply voltage range for the FUSE ROM domain.
I found "During functional operation,this pin is a no connect" on page 78 in "SPRS717D–OCTOBER 2011–REVISED MAY 2012".
But in "AM335X 15X15 ICE BOARD",I found this pin is connected to VDD2_SMPS,which is the power of VDD_CORE.
2,EXTINTn,External Interrupt to ARM Cortext A8 core
Since this pin is interrupt input, should I drive it high or low?or left it unconnected?
I found this unconnected in "AM335X 15X15 ICE BOARD" and was driven at other references.
3,EXT_WAKEUP,Dedicated Input Pin for External Wake Events
If we don't use external wake function,what should we do to this pin?
Since these pins are dedicated input pins,we cann't configure them as output GPIO.
So I think we should drive them to a fixed value.
