パラメーター デフォルト値 Description

Gen 3 Requested equalization far-end TX preset vector

0 - 65535

0x00000004 (for P-Tile)

0x00000020 (for F-Tile devices with OPNs that end with the suffix VR0, VR1, or VR2)

0x0000030a (for F-Tile devices with OPNs that end with the suffix VR3 or AA)

0x00000200 (for R-Tile Rev. A)

0x00000010 (for R-Tile Rev. B)

Gen3要求フェーズ2/3遠端TXプリセットベクトルを指定します。ほとんどのデザインでは、デフォルトとは異なる値を選択することはお勧めしません。

Gen 4 Requested equalization far-end TX preset vector

0 - 65535

0x00000270 (for P-Tile)

0x00000020 (for F-Tile devices with OPNs that end with the suffix VR0, VR1, or VR2)

0x0000036a (for F-Tile devices with OPNs that end with the suffix VR3 or AA)

0x00000008 (for R-Tile Rev. A)

0x00000088 (for R-Tile Rev. B)

Specifies the Gen 4 requested phase 2/3 far-end TX preset vector.

Choosing a value different from the default is not recommended for most designs.

Gen 3 Requested equalization far-end TX preset vector

0 - 65535

0x00000200 (for R-Tile Rev. A)

0x00000300 (for R-Tile Rev. B)

Specifies the Gen 5 requested phase 2/3 far-end TX preset vector.

Choosing a value different from the default is not recommended for most designs.

Predetermined number of lanes (for R-Tile and F-Tile)

Enable Avalon-HIP slave interface

ON、OFF

Off

Enable HIP interface

注: This interface is automatically enabled in Root Port mode. Hence, the parameter is not available for user modification in Root Port mode.

Enable Prefetchable Memory 64-bit address support (Root Port mode only)

ON、OFF

Off

When in RP mode, indicates that the prefetchable memory range supported is 64-bit.

注: This feature is supported for P-Tile and F-Tile only.

Disable Equalization Phase 2 and Phase3

ON、OFF

Off

When this parameter is selected, there is no Equalization in Phase 2 and 3 during PCI Express link training.

注: This feature is only supported for R-Tile and with Root Port mode.
