Ethernet Controller I210 —PCIe Programming Interface

590

A description of the registers is provided in the following sections.

9.3 Mandatory PCI Configuration Registers

9.3.1 Vendor ID (0x0; RO)

This value can be loaded automatically from Flash address 0x0E at power up or reset. A value of

0x8086 is the default for this field at power up if the Flash does not respond or is not programmed.

Note: To avoid a system hang situation, if a value of 0xFFFF is read from the Flash, the value of the

Vendor ID field defaults back to 0x8086.

9.3.2 Device ID (0x2; RO)

This is a read-only register. This field identifies individual I210 functions. It can be auto-loaded from the

Flash during initialization with a different value. The following table lists the possible values according

to the SKU and functionality.

2. CTRL_EXT.Link_Mode field value 00b (10/100/1000 BASE-T internal PHY mode).

3. CTRL_EXT.Link_Mode field value 11b (SerDes).

4. CTRL_EXT.Link_Mode field value either 01b (1000BASE-KX) or 11b (SerDes - 1000BASE-BX). User option to enable Clause 37 Auto-

negotiation.

5. CTRL_EXT.Link_Mode field value 10b (SGMII).
