Hello,

Let me understand your use-case. I am assuming you are not using I2C in this case.

Also could you please provide some more details regarding "CCS usage".

Thanks

Hello,

Yes, you are right, I'm not using I2C and according to the AOP datasheet SDA and SCL optionally configurable as general purpose I/O. Then, how can I activate/deactivate them from the microcontroller program?

Hello,

Please check the following registers to configure SDA and SCL as GPIO @https://www.ti.com/lit/ug/swru522e/swru522e.pdf:

1) Section 25.6.17 ICPFUNC Register: For setting GPIO mode

2) Section 25.6.18 ICPDIR Register : For setting directions

You can refer to other register in the same sections as well for complete details.

Thanks

Yogesh
