In normal functional mode, these bits
MUST
be set to zero.

MTR
MTIE Reset
When this bit is low, the MTIE circuit applies a phase offset between the reference input
clock and the DPLL output clock and the phase offset value is maintained. When this bit
is high, MTIE circuit is in its reset state and the phase offset value is reset to zero,
causing alignment of the DPLL output clocks to nearest edge of the selected input
reference.
6 - 5
PRS1 - 0
Preferred Reference Selection Bits
These bits select the preferred reference from one of the input references.
T
hey are used
only if the PMS2-0 bits are set to 001. Otherwise, these bits are ignored.
4 - 2
PMS2 - 0
Preference Mode Selection Bits
These bits select one of the preference modes:
If in automatic mode with a preferred reference (PMS2-0 = 001 and FDM1-0 = 00), the
automatic state machine will only switch between two references (as per Table 8). Please
see Section12.1.3.2, “Automatic Reference Switching With Preferences“ on page 41 for
more details.
