The default value represents far upper limit for all reference frequencies, which is +11.287 ppm (Stratum 3 compliant
value), regardless of the reference frequency.
The name ’upper’ is based on frequency.

Multiple-Period Far Upper Limit Bits: Total binary value of these bits and the
MPFULRU register bits defines the far upper limit for the multiple period count of any
reference input, minus 1. The unit of the binary value is measured in 100 MHz clock
periods.
