M24LR64-R
26.4
Write Single Block
On receiving the Write Single Block command, the M24LR64-R writes the data contained in
the request to the requested block and reports whether the write operation was successful
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.
During the RF write cycle W
Otherwise, the M24LR64-R may not program correctly the data into the memory. The W
time is equal to t
