TCO Modes
5.14.2.1
TCO Legacy/Compatible Mode
In TCO Legacy/Compatible mode the Intel Management Engine and Intel AMT logic and
SMBus controllers are disabled. To enable Legacy/Compatible TCO mode the TCOMODE
bit 7 in the ICHSTRP0 register in the SPI device must be 0.
Note:
SMBus and SMLink may be tied together externally, if a device has a single SMBus
interface and needs access to the TCO slave and be visisble to the host SMBus
controller.
