Enabling Peripheral Expansion Applications Using the HIC

C2000™ microcontrollers offer several differentiated peripherals, enabling real-time control intensive industrial and digital power applications. The Host Interface Controller (HIC) allows an external application controller to take advantage of the C2000’s differentiated peripherals and processing capabilities through a commonly supported Asynchronous interface. For instance, the Fast Serial Interface (FSI) is capable of supporting low-latency and robust high-speed communication across isolation in a system. Using the HIC, any application processor can integrate FSI on to their system to perform high speed communication over isolation. This application report introduces example HIC applications and helps to select the right configuration of the HIC peripheral as per the application requirements.

You are expected to be familiar with the HIC chapter of an applicable C2000 Device's Technical Reference Manual (TRM), which covers the complete feature set and register definitions.
