See Section 14.6 of the PMBus Specification Part II.

The MAX15301 hardware has 8-bit resolution for the minimum input voltage required for regulation,

The desired value of VIN_OFF is retained in memory, regardless limitations imposed by the 8-bit fault

limit resolution, but the read-back value is based on actual hardware register settings.
