Hi
I did think about that initially, but what with the VPBDIV 
corruption etc, I thought that changing the polarity on the fly 
might be a bit more trouble than it was worth. So I sacrificed an 
extra pin to do the second edge.

I could still give it a try and see what happens, I will just set 
the other pin back to GPIO.
