NOTES:
1. This parameter is based on characterization data.
2. 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.
3. This parameter is not 100% tested.
