Type-level enum identifying the Dfll control loop mode
The types implementing this trait, i.e. OpenLoop, FromPclk and
FromUsb, are type-level variants of Mode, and they determine whether
the DFLL operates in closed-loop mode, and if so, which Reference clock
to use.
Mode is the type-level equivalent of DynMode. See the documentation on
type-level programming and specifically type-level enums for more
details.
