The PCH provides an System Management Bus (SMBus) 2.0 host controller as well as an SMBus Slave Interface.
- Host Controller: Provides a mechanism for the processor to initiate communications with SMBus peripherals (slaves). The PCH is also capable of operating in a mode in which it can communicate with I2C compatible devices.
- Slave Interface: Allows an external master to read from or write to the PCH. Write cycles can be used to cause certain events or pass messages, and the read cycles can be used to determine the state of various status bits. The PCH’s internal host controller cannot access the PCH’s internal Slave Interface.
