CFG[17:0]
Configuration Signals:
The CFG signals have a default value of '1' if not
terminated on the board.
• CFG[1:0]:
Reserved configuration lane. A test point may be placed on
the board for this lane.
• CFG[2]:
PCI Express* Static x16 Lane Numbering Reversal.
— 1 = Normal operation
— 0 = Lane numbers reversed
• CFG[3]:
Reserved
• CFG[4]: eDP enable
— 1 = Disabled
— 0 = Enabled
• CFG[6:5]: PCI Express Bifurcation:
— 00 = 1 x8, 2 x4 PCI Express
— 01 = reserved
— 10 = 2 x8 PCI Express
— 11 = 1 x16 PCI Express
•
CFG[17:7]:
Reserved configuration lanes. A test point may be placed
on the board for these lands.

RSVD_NCTF
RESERVED:
All signals that are RSVD and RSVD_NCTF must be left
unconnected on the board. However, Intel recommends that all RSVD_TP
signals have using test points.
