If SPC = '1' and the stop endpoint command is executed, after a Short Packet condition has been detected, but before the end of the TD has been reached, (i.e. the TD is in progress for pipe), then a Transfer Event TRB with its Completion Code set to Stopped - Short Packet and its TRB Transfer Length set to value of the EDTLA shall be forced for the interrupted TRB, irrespective of whether its IOC or ISP flags are set. This Transfer Event TRB will precede the Command Completion Event TRB for the command, and is referred to as a Stopped Transfer Event.
