Definition
Configures DTE rate, stop bits, parity and number of
character bits.
Requests current DTE rate, stop bits, parity and number of
character bits.
RS-232 signal used to tell the DCE device the DTE device
is now present.
Unhandled requests are STALLed.
21.4.3.2 Communication Endpoints
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.
