HDC2010: Specifications of I2C

Dear Toshi -

Please see page 6 of the datasheet (Section 6.7 and Figure 1)

Dear Josh

As the drawing of specifications did not have an arrow, I confirmed it.
Please tell me which time of the timing chart it is using an arrow.

Regards,
Toshi

Toshi - 

In I2C communications, START condition is defined by a high to low transition on the SCL line while SDA is high. There are no timings associated with that definition. 

Dear Josh

What value is the maximum of "Shutdown entry delay" (tSTART=15msec) in specifications?

Regard,
Toshi

Toshi-

This is the time the part waits for further I2C traffic before going to sleep. This device is made for ultra low power systems, and it will go to sleep to draw very low current while not being used.  

Dear Josh

Thank you very much.
This specifications of tSTART are unrelated to the communication timing of I2C.
Is this understanding all right?

Regards,
Toshi
