The API layer is available for user access and is supposed to be the only interfaces for the user. A module in the API layer is not necessary a direct mapping of a hardware peripheral but provides a higher functional model for the user.

For example, the Endpoint API module models the endpoint usage which covers the configuration of ENETC peripheral, port peripheral, Station interface peripheral, etc... It abstracts the hardware details to provide a simpler model to interact on the network.

The modules APIs require a handle (xxx_handle_t pointer) which is used to get the appropriate context.

NETC is divided into 4 main groups:

• Endpoint: NETC works as endpoint
• Switch: NETC works as switch
• Timer: Timer functionalities
• MDIO: MDIO functionalities
