You have more issues to consider beyond just whether the pin functions are available, be-
cause every change to the topology of a circuit has at least
some
impact. There are changes
to the transmission line behavior, changes to the capacitance and inductance of the signal,
and more.
At low speeds, such as below 1 MHz, most of these effects can be ignored, but it is import-
ant to pay attention to the electrical specifications in the data sheet of any device you are
using. When you try out your circuits, use an oscilloscope at various points on the signific-
ant signals to ensure that you see the behavior you expect. Don't assume that just because
things seem to be generally working that there isn't something marginal about your con-
struction. The manufacturer of your capes likely didn't think a lot about them being used
with other capes.
