Device Sends the Last
Data Payload to Host
Data IN
Note: A NAK handshake is always generated at the first status stage token.
Note: Before proceeding to the status stage, the software should determine that there is no risk
of extra data from the host (data stage). If not certain (non-predictable data stage length), then
the software should wait for a NAK-IN interrupt before proceeding to the status stage. This pre-
caution should be taken to avoid collision in the FIFO.
