I don't understand where you are seeing this weird "00 0x10". Are you saying that you see this when running in hardware? When running code? Where are you seeing this?

Thank you for your response.

I can see this while it is running in the hardware,

The ip is implemented and programmed in the CPLD and i did a i2c probe command from the host (processor).

Then i see the unknown "00" address along with the valid I2C address "10".

i tried replacing the intel i2c with a custom made I2C IP with minimum functionality and couldn't see any unknown address other than the valid i2c address, that's how i concluded that this unknown 00 is coming from the intel i2c ip.
