Yeah, I got stung badly with BSF's once.

Be extra careful when a IO pin is set for analog but is used as a
digital output.

The digital IO pin will always be set to 0 when BSF etc is used on that
PORT.

That is because an analog pin set as digital out will always read as 0.
There is a AND gate in the read path of the analog IO pins and the
output of this is Logic 0 when analog is selected.
