Fast Read Multiple Block
On receiving the Fast Read Multiple Block command, the LRI2K reads the requested 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, a
value 06h in the “number of blocks” field causes the LRI2K to read 7 blocks. 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. The data rate of the response is
multiplied by 2.
