I probably shouldn't have switched the order, but it is too late now.
That is the direction they are on page 1-6, so I just copied how it was
layed out (and I was thinking in Verilog at that point; here is the
result :-)). Here is what I meant by the numbers:
> pins_down[4:6]=g[5:7]
this means that pins[4] on the falling edge of clock is g[5], pins[5] on
the falling edge is g[6], and pins[6] on the falling edge is g[7].

same thing here:
> pins_up[0:2]=b[0:2]
pins[0] on the rising edge is b[0], etc.

does that clear things up?
