Method to handle SCSI messages as a target

摘要

In a SCSI controller, unexpected messages are automatically received in response to an attention signal by receiving all of the bytes constituting the message and storing those bytes in an available register file selected from a plurality of register files in the controller. Once the entire message has been received and stored, a determination of an appropriate response is initiated. The register files are also used to hold selection information during a bus-initiated selection, so additional architecture is not required.
