This logic looks funny, especially the test for !enable in the second
case (which should always be true).  I think the intention here is to
look for "apll_enabled has done an interesting transition (0->1 or
1->0)" - it'd probably be clearer to look for that directly.

The use of INPUT and OUTPUT widgets here looks really odd - I'd at least
except the AIF widgets to be actual AIF widgets.
