Preferred Reference Selection Bits
These bits select the preferred reference from one of the input references. They 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 Section 12.1.3.2, “Automatic Reference Switching With Preferences“ on page 40 for
more details.
