Hello Marcelo,
i fix a compiler warning from pdc202xx.c.
The "default:" value in the switch was empty. Gcc don`t like
this. We don`t need this one.
error:

Correct solution is not to remove the "default:" but to add a "break;"

So people start wondering if somehow the content of the default case got
deleted by mistake? Better not. Plus it is needless (source) code bloat.

So comment it:
default:
break; /* Does nothing */
A switch without a default case is simply asking for trouble in the
long run.
