Read Multiple Block
When receiving the Read Multiple Block command, the LRI2K reads the selected blocks
and sends back their value in multiples of 32 bits in the response. The blocks are numbered
from '00 to '3F' in the request and the value is minus one (–1) in the field. For example, if the
“number of blocks” field contains the value 06h, 7 blocks will be read. The maximum number
of blocks is fixed at 64. During Sequential Block Read, when the block address reaches 64,
it rolls over to 0. The Option_flag is supported.
