Cross examples

Hi

In 5.10.3.1, both of the examples for cross have

parameter integer dir = +1 from [-1:0] exclude 0;

I think that ought to be "from [-1:1] exclude 0", to allow choosing
negative and positive going edges for the sampling clock. As it stands
the examples must be instantiated with 'dir' set to -1.
