○ SDA data is latched into the chip at the rising edge ○
of SCL clock.
○ Output data toggles at the falling edge of SCL clock.

Fig.1-(e) WP Timing Of The Write Cancel Operation
○ For WRITE operation, WP must be "Low" from the rising edge of the
clock (which takes in D0 of first byte) until the end of tWR. (See
Fig.1-(d) ) During this period, WRITE operation can be canceled by
setting WP "High". （ See Fig.1-(e) ）
○ When WP is set to "High" during tWR, WRITE operation is
immediately ceased, making the data unreliable. It must then be
re-written.
