Fast Read Multiple Block
On receiving the Fast Read Multiple Block command, the M24LR16E-R reads the selected
blocks and sends back their value in multiples of 32 bits in the response. The blocks are
numbered from 00h to 1FFh 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, seven blocks are read. The
maximum number of blocks is fixed to 32 assuming that they are all located in the same
sector. If the number of blocks overlaps sectors, the M24LR16E-R returns an error code.
The Protocol_extension_flag should be set to 1 for the M24LR16E-R to operate correctly. If
the Protocol_extension_flag is at 0, the M24LR16E-R answers with an error code.
The Option_flag is supported. The data rate of the response is multiplied by 2.
The subcarrier_flag should be set to 0, otherwise the M24LR16E-R answers with an error
code.
