C Interface
The Broadwell-DE integrates a SMBus 2.0 controller that provides an interface to manage
peripherals such as the Serial Presence Detection (SPD) on the RAM, thermal sensors, PCI
cards, etc. There are four SMBus ports on the SoC. The slave interface allows an external
microcontroller to access system resources. The diagram below shows the SMBus architecture
of each CPU.
