CFG4
R393 *3.01K_1%_04
CFG7 - Reserved - Temporarily used for
early Clarksfield samples.
Clarksfield (only for early samples
pre-ES1) - Connect to GND with 3.01K
Ohm/5% resistor
CFG7
Note: Only temporary for early CFD
samples (rPGA/BGA) [For details
please refer to the WW33 MoW and
sighting report].
For a common motherboard design (for
AUB and CFD), the pull-down resistor
should be used. Does not impact AUB
functionality.
