Hello TI,

When the ADDR pin sample to define the Device address? is it at power up or out of Reset or some other state?

Please advise

Thanks

Hi Asaf,

I believe on power up and reset conditions.

I would need to double check, but I don't think this device can dynamic address.

Tyler

Thanks Tyler,

I just want to verify the ADDR pin sample at out of Reset and not other scenario.

In general, these devices do not have a register for the address, and compare the address bit against the current state of the ADDR pin when the I²C transaction happens.
