NOTES:
4. 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.
5. The device goes into Standby: 200ns after any stop, except those that initiate a high voltage write cycle; t
WC
after a stop that initiates a high
voltage cycle; or 9 clock cycles after any start that is not followed by the correct Device Select Bits in the Slave Address Byte.
