Part Number: DS90UB941AS-Q1

Here is the H/W block diagram for my project.

As below, Touch IC's I2C address are duplicated between port 0 and port 1.

But I'd like to control the Touch IC separately.

In this case, Is it possible control the Touch IC separately?

If it is possible, please let me know how to configure register.

Thanks,

Hi aiden,

you can read and write from these Touch IC's separately by using I2C pass-through on the 941AS and then selecting which port you want to write to and read from using the PORT1_SEL and PORT0_SEL registers.
