This command sets the Start Address from which the ASIC Flash Read (Section 3.50) command will start reading, and Read Length. Though each ASIC Flash Read command has its own requested length, this Read Length is used to tell the ASIC when to stop the read operation. The Read Length specifies the total number of bytes to be read from the Flash (which will be read using repetitive ASIC Flash Read commands with their own lengths, limited to a maximum of 255 bytes per command). The Piccolo keeps track of the number of bytes read (sum of read lengths of the individual ASIC Flash Read Commands). When the number of bytes read becomes equal to the Read Length set through this command, the Piccolo performs certain register writes to disable the read operation.
