1.3 Host Interface (HIF)

The HIF is responsible for handling the communication between the host driver and the WINC firmware. This includes interrupt handling, DMA and HIF command/response management. The host driver communicates with the firmware in the form of commands and responses formatted by the HIF layer.

The interface is defined in the m2m_hif.h file.

The detailed description of the HIF design is provided in Host Interface Protocol.
