M24LR16E-R
26.24
When configured in the RF busy mode, the RF WIP/BUSY pin is tied to 0 from the SOF that
starts the ReadCfg command to the end of the M24LR16E-R response.
When configured in the RF write in progress mode, the RF WIP/BUSY pin remains in high-Z
state.
WriteEHCfg
On receiving the WriteEHCfg command, the M24LR16E-R writes the data contained in the
request to the Configuration byte and reports whether the write operation was successful in
the response. The Protocol_extension_flag should be set to 0 for the M24LR16E-R to
operate correctly. If the Protocol_extension_flag is at 1, the M24LR16E-R answers with an
error code.
The Option_flag is supported, the Inventory_flag is not supported.

otherwise, the M24LR16E-R may not program correctly the data into the Configuration byte.
