2.
Delays are measured from the time VCC is stable until the specified operation can be initiated. These parameters are periodically sampled and not
100% tested.
Typical values are for TA = 25˚C and VCC = 5.0V

Notes:1. _{tWC 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.
