Hi Christian,
No, DOUT and DIN are only for audio data transfer. Control Registers can only be written using SCL and SCA (I2C).

am sending command to the chip through i2c but its not responding, what is the coreect i2c address and smartdm address for a single chip used as a standalone slave
Hi Christian,
See the Figure below:
Your I2C address/SMARTDM address is set by control register 2 for the I2C portion and is 0000 for the SMARTDM portion.

if the control registers cannot be written to through DIN but i2c how then can i write to the register 2 to set the i2c address, which initial address should i use as i2c address when when writing to register 2 to change the i2c device address,
Hi Christian,
See the table below for the register description. The default address for a single device would be 1000000.
Best regards,
Jeff McPherson
thank you so much, i can read data, but the data i write into the register is not the same with what i read out from it
Hi Christian,
Can you give an example of what you are seeing?
Take care that you are setting the R/W bit correctly and following the read and write instructions outlined in the data sheet.
Best regards,
Jeff McPherson
