FAST-MODE and STANDARD-MODE
FAST-MODE and STANDARD-MODE are of same actions, and mode is not changed. They are distinguished by action speeds. 100kHz
action is called STANDARD-MODE, and 400kHz action is called FAST-MODE. This action frequency is the maximum action frequency,
so 100kHz clock may be used in FAST-MODE. When power source voltage goes down, action at high speed is not carried out,
therefore, at Vcc = 2.5V ~ 5.5V, 400kHz, namely, action is made in FASTMODE. (Action is made also in STANDARD-MODE) Vcc =
1.8V ~ 2.5V is only action in 100kHz STANDARD-MODE.

At write execution, in the area from the DO taken clock rise of the first DATA (1), to tWR, set WP =
"LOW".
By setting WP "HIGH" in the area, write can be cancelled.
When it is set WP = "HIGH" during tWR, write is forcibly ended, and data of address under access is not
guaranteed, therefore write it once again.
