P3T1035x(temp sensor) How to read the pointer register in I3C mode

Can the pointer register setting access with I3C communication?
Because It aborts when receiving T bit after receiving data, sending Slave address and sending the pointer value,, it looks like I2C Ack/Nack is returned from the P3T1035x.

it looks like the pointer register accesses in I2C mode in the spec sheet 7.5.1 . Timing chart etc,.

I want to know the correct spec.

Hi Tomas

Thank you very much for replying. I understood it.

I currently connect an i3c controller that based on the MIPI Alliance and the temp sensor.

After accessing with ccc in i3c mode, in order to access the pointer byte, I need to switch to i2c mode. In other words, when switching to i2c mode, I need to start over from the initialization sequence of i2c mode, is that correct?

Hi,

The pointer register access (pointer byte) is only applicable in I2C mode.
