Terminate Upload Request and Response
Request: LLLL 58 02 RRRR
Response: LLLL 58 HH 03 RRRR or LLLL 58 HH 08 RRRR
The terminate upload command is used to remove the attached device from
upload mode. The attached device will return the response LLLL 58 02
RRRR (in response to a LLLL 58 01 RRRR YYYY command) when all data
has been uploaded. This response notifies the host that the upload
operation is complete and that all data has been returned. The attached
device will remain in the upload mode until it receives a terminate upload
command.
If a terminate upload command is sent to the attached device before it
notifies the host that the upload is complete, the secondary will respond
with LLLL 58 HH 08 RRRR which indicates the upload was terminated
prematurely.
Upload sequence count which is initially set to 0 and
incremented by 1 on each subsequent upload request. The
response will contain the same value as was sent to the
attached device during the request. The YYYY field can
also be used to retrieve the previous two responses, i.e.,
the response just returned, and the one immediately
preceeding it. This process is known as rollback.
