I have K60 tower:  MK60FN1M0VLQ12.


I have general questions about unused pins.

1. What is the state of uninitialized pins? Tri-state, Input, or output?

2. What is your suggestions to initialize unused pins if it is necessary to to be initialized?

    as disabled (analog)  - MUX (0)

    as GPIO - MUX (1)  as input pull-up, pull-down, or output?

3. is disabled (analog) - MUX(0) the same as tri-state?


Thank you,

David Zhou
