DS90UB954-Q1: The speed of I2C

Part Number: DS90UB954-Q1

Hi,

When I read the datasheet the description of I2C makes me puzzled.

It says that the default speed of 953 is 74Kbit/s and 954 is 100Kbit/s on page60 of 954datasheet 

And remote rate depends on the settings for the proxy I2C master 

But the settings for the proxy I2C master is 100Kbit/s.

I don't know how fast the speed of 953 I2C is now.

The speed of host is 400Kbit/s in my design now, if I do not change any registers about I2c,is the speed of 953 is 100Kbit/s?

Looking forward to your reply.

Yue
