template <, >typename SelfType::ValueType fraction_denominator ()The raw clock frequency in MHz. Complex representation used by DG1.
Raw clock frequency = integral frequency + fractional frequency
Integral frequency = `integer` + 1
Fractional frequency = `fraction_numerator` / (`fraction_denominator` + 1)
`fraction_denominator` must be zero if `fraction_numerator` is zero.
Only `fraction_numerator` values 0-2 are documented as supported.
All these fields must be zero on Kaby Lake and Skylake.
