Read Block
Use this command to read a block of words from the destination. Use the
address (L ADDR) field to specify a starting logical word address; keep
the address constant throughout a complete transaction. In the first packet
of a transaction, the packet-offset value is 00. In subsequent packets of a
transaction, use the packet-offset field to specify the word offset (within
the block) at which the read starts for the packet. Use the total-transaction
field to specify the number of bytes to read in the total transaction. Use
the SIZE field to specify the number of bytes to read for the specific
packet.
