X1202
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.
(2) The device enters the program state 200ns after a stop ending a write operation and continues for t
.
WC
(3) The device goes into the timekeeping state 200ns after any stop, except those that initiate a nonvolatile write cycle; t
after a stop
WC
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.
