Functional Description
5.14.2.2.2
Advanced TCO BMC Mode
In this mode, the external microcontroller (BMC) is connected to both SMLink and
SMBus. The BMC communicates with Intel Management Engine through Intel ME
SMBus connected to SMLink. The host and TCO slave communicated with BMC through
SMBus. See Figure 5-8. This mode is enabled when the BMCMODE bit 15 in the
ICHSTRP0 register in the SPI device is 1.
