The default value represents near upper limit for all reference frequencies, which is +9.913 ppm (Stratum 3 compliant
value), regardless of the reference frequency.
The name ’upper’ is based on frequency.

Multiple-Period Near Upper Limit Bits: Total binary value of these bits and the
MPNULRU register bits defines the near 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.
