1 RESET and configuration override data lines are synchronized internally. Setup and hold times must be met only if
recognition on a particular clock is required.

2 During low power STOP, the synchronizers for the RESET input are bypassed and RESET is asserted asynchronously
to the system. Thus, RESET must be held a minimum of 100 ns.
