Communication Endpoints
Table 13-3.
The device also handles some class requests defined in the CDC class.
Table 13-4.
Unhandled requests are STALLed.
There are two communication endpoints and endpoint 0 is used for the enumeration process.
Endpoint 1 is a 64-byte Bulk OUT endpoint and endpoint 2 is a 64-byte Bulk IN endpoint. SAM-
BA Boot commands are sent by the host through the endpoint 1. If required, the message is split
by the host into several data payloads by the host driver.
If the command requires a response, the host can send IN transactions to pick up the response.
The SPI and NANDFlash drivers use several PIOs in alternate functions to communicate with
devices. Care must be taken when these PIOs are used by the application. The devices con-
nected could be unintentionally driven at boot time, and electrical conflicts between SPI output
pins and the connected devices may appear.
To assure correct functionality, it is recommended to plug in critical devices to other pins.

is found.
