1. If D3cold is not supported, the wake-up context is reset (PME_Status and PME_En
2. Refers to bits in the Wake-Up Control (WUC) register that are not part of the wake-
3. The Wake-Up Status (WUS) registers include the following:
• Force TCO - This reset is generated when manageability logic is enabled. It is only
• EEPROM Reset - Writing a 1b to the EEPROM Reset bit of the Extended Device
• PHY Reset - Software can write a 1b to the PHY Reset bit of the Device Control

is 1b. In pass-through mode it is generated when receiving a Force TCO SMBus
command with bit 1 or bit 7 set.
