Figure 26-15. Control Read
A NAK handshake is always generated on the first status stage command.
When the controller detects the status stage, all the data written by the CPU are lost and clear-
ing TXINI has no effect.
The user checks if the transmission or the reception is complete.
The OUT retry is always ACKed. This reception sets RXOUTI and TXINI. Handle this with the
following software algorithm:
Once the OUT status stage has been received, the USBB waits for a SETUP request. The
SETUP request has priority over any other request and has to be ACKed. This means that any
other bit should be cleared and the FIFO reset when a SETUP is received.
The user has to take care of the fact that the byte counter is reset when a zero-length OUT
packet is received.
