Hello Hidetoshi,

We don't have the information about the parameters you are looking for, but if you really need them, we can measure an estimated value of those parameters.

Hello Aldo,

Thank you for your kind offer. 

Could you give me an estimated value of those parameters?

Because my customer need those parameters.

Hi Hidetoshi-san

Please, see my comments:

How long does TFP410 need to keep the low time for the I2C state machine is reset?

A= The ISEL/RST terminal should be low for at least 100uS.

Also how long does it takes time until actual reset for TFP410 after ISEL/RST are brought low and then back high?

A= It takes around 700 mS.

Regards,

Aldo.

Hello Aldo,

I appreciate your support.

I'd like to ask you some additional questions.

• We can write I2C data after it takes around 700ms.  I2C data isn't reflected within 700ms. Is my understanding correct?

• I think 700ms is long time, generally. Could you tell me the reason why does it takes around 700 ms?

I've encountered this before.. Yes, the I2C data is not indeed visible with 700ms... at least, that's what I think..

Hello Aldo,

I appreciate your support.

I understood it.
