How are clock generated in PSoC?
This might help -
You can also refer Technical reference manuals for more details on clocks in PSoC 1. Here is the link for TRMs-
rjvb, you see the confusion, the TRM uses "Powered Down" vs "Powered Off",
so thats why the sugestion for the tech case posting.
But I will take you word that "Powered Down" does not mean power to a low power
state, rather it means completely off.
