1. Preliminary data.

2. Only for M24xxx-HR6.

3. Characterized value, not tested in production.

4. The device is not selected after power-up, after a READ command (after the Stop condition), or after the

completion of the internal write cycle tW (tW is triggered by the correct decoding of a WRITE command).
