Problem Description:



Solution 1:

5200: Same to 4k, can be use on I, O, I/O for both pullup and pulldown.



Solution 2:




Using PULLUPs and PULLDOWNS with Inputs/Outputs

2k:  Although there are pullups on unused I/O before configuration, after
	configuration there are no usable I/O pullups after configuration.

3k:  Pullups only, but can ONLY be use on Inputs

4k and 5200:  Pullups and pulldowns, can be used with I, O, I/O.  Just place on
