NOTES:
1. The device enters the active state after any start, and remains active until: 9 clock cycles later if the device select bits in the slave address byte
are incorrect; 200ns after a stop ending a read operation; or t_WC after a stop ending a write operation.
2. The device goes into standby: 200ns after any stop, except those that initiate a nonvolatile write cycle; t_WC after a stop that initiates a nonvolatile
cycle; or 9 clock cycles after any start that is not followed by the correct device select bits in the slave address byte.
3. V_IL min. and V_IH max. are for reference only and are not tested.
