M24LR64-R
26.3
Read Single Block
On receiving the Read Single Block command, the M24LR64-R reads the requested block
and sends back its 32-bit value in the response. The Protocol_extention_flag should be set
to 1 for the M24LR64-R to operate correctly. If the Protocol_extention_flag is at 0, the
M24LR64-R answers with an error code. The Option_flag is supported.
