MPC5676R pull up/down

I am new to this processor and I have a few questions about its pins during reset/configuration.


I read in the reference manual that the state of the WKPCFG pin is sampled during processor reset and the state of that pin determines how the eTPU and eMIOS pins are pulled (up/down) during reset.


1. Is there a way to specify each pins pull up/down setting independently. If so, how?

2. Can the pins be tri-stated?

3. Can the pins pull up/down configuration be changed after reset or is it always the same after reset as during reset?

4. Where are the answers to these questions in the processor documentation?
