Has anybody experienced an issue with the PLP_A not working properly.
 

I have 4 inputs we want to read in on Port A and have used PLP_A = %0000

Now when checking it with a HI-Z Fluke Multimeter it tells me the pins float...

and my code does really strange things ( obviously seeing floating pins ..hi and lo's ....)

 

As soon as I connect resistors to the pins as pull ups ( some 4.7K even 10K type)

my code behaves as it should...

 

Cheers
