Dear Support team;

Our customer is planning the following structure.

(The red line is I2C bus)

Can the MCU access to 913A(1) and 914A(2) ?

I think that the MCU can access to 914A(3) and 913A(3) and 913A(2) and 914A(1).

Could you tell me?

Best Regards,

Hi,
The MCU could access 913A(1) and 914A(2) if 0x21[7] I2C Pass-Through All is set to 1 on 914A(3).

Sincerely,
Charley Cai
