  56          Configures the direction of general port A bits.  1 is out, 0 is in.
  57          This is often totally different depending on the product used.
  58          There are some guidelines though - if you know that only LED's are
  59          connected to port PA, then they are usually connected to bits 2-4
  60          and you can therefore use 1c.  On other boards which don't have the
  61          LED's at the general ports, these bits are used for all kinds of
  62          stuff.  If you don't know what to use, it is always safe to put all
  63          as inputs, although floating inputs isn't good.
