(3) Data Stage (Control-Out)
The firmware first analyzes the command data that is sent from the host in the setup stage, and
determines the subsequent data stage direction. If the result of command data analysis is that
the data stage is out-transfer, data from the host is waited for, and after data is received
(EP0oTS in UIFR0 is set to 1), data is read from the FIFO. Next, the firmware writes 1 to the
EP0o read complete bit, empties the receive FIFO, and waits for reception of the next data.
The end of the data stage is identified when the host transmits an IN token and the status stage
is entered.
