Configures the direction of general port A bits. 1 is out, 0 is in.

This is often totally different depending on the product used.
|
|
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.
