If multiple pages are sent during the DATA OUT phase, they must be
sent in ascending order according to page code. Otherwise, the command
terminates with a CHECK CONDITION status, sense key set to ILLEGAL
REQUEST, and additional sense code set to INVALID FIELD IN
PARAMETER LIST. The same status is returned if an unsupported Page
Code appears in any header or if the specified page cannot be cleared.
