Abstract:
1. A system comprising: an interface; a transmitter/receiver coupled to the interface; and a storage array coupled to the interface; wherein the transmitter/receiver is operable to: monitor a write sequence whenever a respective one of the received commands is identified as a write command targeting the storage array, wherein the write sequence is initiated by the identified write command; discard the identified write command when a ULPI DIR signal issued by the transmitter/receiver is asserted before the end of a predetermined period of observation during the write sequence; and allow the write sequence to complete when a ULPI STP signal received by the transmitter/receiver and the ULPI DIR signal are not asserted before the end of the predetermined period of observation during the write sequence; wherein the predetermined period of observation is shorter than the duration of the write sequence.
