Figure S.5 Software download
The NT positively acknowledges an end download message only after it has performed whatever
operations may be necessary – such as storage in non-volatile memory – to accept an immediate activate
or commit message from the DPU. As illustrated in Figure S.6, the NT responds with a device busy result
code until these operations are complete, and the DPU periodically retries the end download command.
The DPU includes a timeout to detect an NT that never completes the download operation.
