FAST-MODE and STANDARD-MODE are of same actions, and mode is 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.
