There are some guidelines though - if you know that only LED's are
|
|
connected to port PA, then they are usually connected to bits 2-4
|
|
and you can therefore use 1c. On other boards which don't have the
|
|
LED's at the general ports, these bits are used for all kinds of

stuff. If you don't know what to use, it is always safe to put all

as inputs, although floating inputs isn't good.
