KW36, without radio

Have a new version of a board using KW36Z, but this one will not be using the radio aspects of the chip at all.

And yes, we do wish to use the KW36Z for this board.


Obviously there are things that can be done in software to disable the radio sections of the chip.


I'm wondering what can be done in hardware.

I can find no guidelines for safe/appropriate connections when not using the radio.

This includes power for RF (VDD_RFx), the antenna pins, etc.


The chip will be operating in bypass mode, as there is already a 3.3V supply on board.

Sleep/quiescent current levels are a very significant issue.
