Section 23 USB Function Controller
(5) Status Stage (Control-Out)
The status stage in control-out starts with in-token from the host. In in-token reception at the start
of status stage, an EP0o transfer-request interrupt occurs since no data is in EP0i FIFO. The
application acknowledges that the status stage has started by the interrupt. To transfer 0-byte data
to the host, no data is written to the EP0i FIFO, and 1 is written to the EP0i packet-enable bit.
Therefore, 0-byte data is transferred to the host in the next in-token, and control transfer is
completed.
However, after the application completes all processing related to the data stage, write 1 to the
EP0i packet-enable bit.
