5.4 Standby Mode
The AT24CS16 features a low‑power Standby
                        mode that is enabled when any one of the following occurs:
    - A valid power-up sequence is performed (see Power-Up Requirements and Reset Behavior).
 - A Stop condition at the end of a valid I2C transaction is received by the device unless it initiates an internal write cycle (see Write Operations).
 - An internal write cycle is completed (see Write Operations).
