T0_DPLL_operating_mode
This field is used to control the state of the internal
finite state machine controlling the T0 DPLL. A value
of zero is used to allow the finite state machine to
control itself. Any other value will force the state
machine to jump into that state. Care should be
taken when forcing the state machine. Whilst it is
forced, the internal monitoring functions cannot
affect the internal state machine, therefore, the
user is responsible for all monitoring and control
functions required to achieve the desired
functionality.
