Functional Description

The SMLink interfaces are controlled by the Intel® CSME.

SMLink0 is mainly used for integrated LAN. When an Intel LAN PHY is connected to SMLink0, a soft strap must be set to indicate that the PHY is connected to SMLink0. The interface will be running at the frequency of up to 1 MHz depending on different factors such as board routing or bus loading when the Fast Mode is enabled using a soft strap.

SMLink1 can be used with an Embedded Controller (EC) or Baseboard Management Controller (BMC).

Both SMLink0 and SMLink1 support up to 1 MHz.

Note: Access to the PCH thermal sensor should be via eSPI. as the SMLink 1 is disabled in Consumer platforms.
