Abstract
A data storage device is disclosed wherein a host interface state machine receives an access command from a host, the access command identifying a plurality of logical block addresses (LBAs). A host interface processor generates at least one control structure executed by the host interface state machine in connection with servicing the access command. The host interface processor directs a master processor to execute the access command, and the master processor updates a LBA register in connection with executing the access command. The host interface state machine executes the control structure to compare a target LBA to the LBA register and communicates with the host in response to the comparison.
