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.
In the illustration above Autovalid validates a bank as full, although this might not be the case, in order to continue processing
data and to send to DMA.
