I just wanted to say, I had to do this before, when a the guy who did the 
PCB for a project made a mistake and reversed all the bits on a port and 
no-one noticed until the code didn't work properly..
As the board was already assembled and hardwired (SMD) we had to use the 
'soft' approach and a LUT was used.
