13. This parameter is not 100% tested.
14. t
WC
is the minimum cycle time to be allowed for any non-volatile Write by the user, unless Acknowledge Polling is used. It is the time from a
valid STOP condition at the end of a Write sequence of a I

C serial interface Write operation, to the end of the self-timed internal non-volatile
write cycle.
15. These are I

C specific parameters and are not directly tested, however they are used during device testing to validate device specification.
