In QPIC v1, SW is needed to write EXEC_CMD register for each Code word and collect any Status related to that CW before issueing EXEC_CMD for next CW. Page scope command, currently supported only for read commands in bam mode, is truly a page mode command where SW is required to issue EXEC_CMD only once for a page. Controller HW takes care of Codeword specific details and automatically returns status associated with each CW to BAM pipe, dedicated for status deposition.
