linking and unlinking a pin based on motion-enabled

This does work as a sample/hold, but it still connects pin limit3.0.in to a signal limit3source. So pin limit3.0.in is not "writable" anymore. I cant set its value in MDI with setp command - and this is my main goal, having it connected to feedback source, and after enable, removing it with a command like unlinkp, which makes pin free to accept value again.

That is a bit tricky because you have 2 states (feedthrough/hold)
plus a load new value function.

You can do the link unlink in a script but not in real time AFAIK

The cleanest implementation might be a specific component

Also it might be possible to use two stacked mux2's, using one mux2
to enter the new value to be latched
