A NAK handshake is always generated at the first status stage token.
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 precaution should be taken to avoid collision in the FIFO.
