Hardware and Software Constraints
Enumeration Process
Communication Endpoints
The USB protocol is a master/slave protocol. This is the host that starts the enumeration send-
ing requests to the device through the control endpoint. The device handles standard requests
as defined in the USB Specification.
Table 13-8.
The device also handles some class requests defined in the CDC class.
Table 13-9.
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 Monitor 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.
