Using PTD6 in FRDM K22F

10 Mar 2015

I have been scratching my head for now a long time. I did my own PCB and hooked up the CHIP ENABLE pin of one of the components in my PCB to PTD6.

I am getting some undetermined behavior. If I set PTD6 to with DigitalOut to HIGH, the components works sometimes. If I don't set PTD6 to anything the component also works sometimes.

It seems there is another signal in PTD6? If so, how can I set PTD6 to be DigitalOut - HIGH?
