Notes:
(1)
The device enters the Active state after any start, and remains active: for 9 clock cycles if the Device Select Bits in the Slave
Address Byte are incorrect or until 200nS after a stop ending a read or write operation.
The device enters the Program state 200nS after a stop ending a write operation and continues for t
WC
.
The device goes into the Timekeeping state 200nS after any stop, except those that initiate a nonvolatile write cycle; t
WC
after a
stop that initiates a nonvolatile write cycle; or 9 clock cycles after any start that is not followed by the correct Device Select Bits in
the Slave Address Byte.
For reference only and not tested.
