> The datasheet for Skylake does not list any such field in that register, 15:0 are the hold time and 31:16 are reserved.
This field, like some other slave-mode related parameters, is not exposed in
desktop-class chipset specs, but exposed in SOCs specs e.g. Arria SOCs and
still has an effect as these devices shares common design.
