*4: The write cycle time (tWR) is the time from a valid stop condition of a write
sequence to the end of the internal program cycle.
Since the device will not acknowledge during the internal program cycle, this can be
used to determine when the cycle is complete. This feature (ACK polling) can be
used to maximize bus troughtput.
*5: The parameter is periodically sampled and not 100% tested.
