I'm designing a board based on the MK64 (the FRDM K64 is my reference design). I do not use the USB features of the MK64. I am using the UART capabilities (using USB dongle to RS485 cable from a far host PC to my controller board, then to UART inputs on the MK64 via a MAX3362 RS 485 Transceiver).
In such case, do I need to connect a voltage to that pin?
Leave it float?
Thanks!

Hi Roy,
Connect VREGIN and VOUT33 together and tie to ground through a 10kΩ resistor.

Ok.
Thank you very much!
I've posted another question regarding un used I/O's and output state at reset.
Can you amswer that also?
