1. Only for devices operating at fC max = 1 MHz (see Table 18).
2. Characterized value, not tested in production.
3. The device is not selected after power-up, after a Read instruction (after the Stop condition), or after the
completion of the internal write cycle tW (tW is triggered by the correct decoding of a Write instruction).
4. Ei inputs should be tied to Vss (see Section 2.3).
5. Ei inputs should be tied to Vcc (see Section 2.3).
