The control-out status stage starts with an IN token from the host. When an IN-token is received at
the start of the status stage, there is not yet any data in the EP0i FIFO, and so an EP0i transfer
request interrupt is generated. The application recognizes from this interrupt that the status stage
has started. Next, in order to transmit 0-byte data to the host, 1 is written to the EP0i packet enable
bit but no data is written to the EP0i FIFO. As a result, the next IN token causes 0-byte data to be
transmitted to the host, and control transfer ends.
After the application has finished all processing relating to the data stage, 1 should be written to
the EP0i packet enable bit.
