NOTES:
2. The device goes into Standby: 200 ns after any STOP, except those that initiate a nonvolatile write cycle. It goes into Standby t
WC
after a STOP
that initiates a nonvolatile write cycle. It also goes into Standby 9 clock cycles after any START that is not followed by the correct Slave Address
Byte.
3. t
WC
is the time from a valid STOP condition at the end of a write sequence to the end of the self-timed internal nonvolatile write cycle. It is the
minimum cycle time to be allowed for any nonvolatile write by the user, unless Acknowledge Polling is used.
4. This parameter is periodically sampled and not 100% tested.
