Functional Description

The Processor provides an System Management Bus (SMBus) 2.0 host controller as well as an SMBus Device Interface.

  • Host Controller: Provides a mechanism for the processor to initiate communications with SMBus peripherals (Devices). The Processor is also capable of operating in a mode in which it can communicate with I2C compatible devices.
  • Target Interface: Allows an external host to read from or write to the Processor . 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 Processor ’s internal host controller cannot access the Processor ’s internal Device Interface.
