FC connected to deserializer.
Powers up.
Writes deserializer configuration
bits and gets an acknowledge.
Writes serializer configuration
bits. Cannot get an acknowledge
(or gets a dummy acknowledge)
if loss-of-lock occurred.
Enables video link by setting
SEREN = 1 (if not enabled
automatically). Cannot get an
acknowledge (or gets a dummy
acknowledge) if loss-of-lock
occurred. Waits for link to be
established (~3ms).
