Notes:
  1. FIVR = Fully Integrated Voltage Regulator. For details, refer to Voltage Regulator.
  2. VccIN_​AUX has a few discrete voltages defined by PCH VID.
  3. VCC1P05_​PROC, for HX SBGA processor the power rail is connected to a platform voltage regulator to supply power to the sustaining power rails

    , P/H/ U 15W-Processor line power rail is connected to VCC1P05_​OUT_​FET rail through a power gate at platform, to supply power to the sustain gated power rails.
  4. VccMIPILP: When MIPI DSI interface is been used, this power rail should be connected to 1.24 V rail.
