The RECEIVE DIAGNOSTIC RESULTS command requests that analysis data requested by a SEND DIAGNOSTIC
command be sent to the Initiator.
- PCV (Page Code Valid) bit of zero indicates that the most recent SEND DIAGNOSTIC command shall define
the data returned by this command. PCV bit of one indicates that the contents of the Page Code field shall
define the data returned by this command.
- Allocation Length specifies the amount of data to be returned to the Initiator. This value may be zero and this
is not considered an error. The Target terminates the Data in phase when all available data has been
transferred or when the number of bytes transferred equals the Parameter List Length.
