If im not using any pins on a IO Bank do i need to connect up its IO VCC? or can i leave this bank completely un powered? Regards Russell Pirie

ESD resistor: 100-Ohms is fine, 1K is Ok if thats what you have. You can always change them later if there is a problem with voltage drop.

Series resistors: something around 30-Ohms is good. Whatever you have close is good enough (eg., as big as 100-ohms would probably be ok - the key is to have them on the PCB ).

Cheers,

Dave
