PINMUX On-The-Fly Selection Between uPP and HPI for C674x

Tsutomu Furuse

Hi.

Would you please tell me if we can change PINMUX selection on-the-fly between uPP pins and HPI pins for C674x?
I understand we can change PINMUX selection on-the-fly. But I'd like to know if there is any specific problem on the uPP-HPI case.
Thanks.

Hi Tsutomu,
I discussed with factory team and got the information that the PINMUX registers are not recommended to modify on the fly for different peripheral selection.
Please refer to the E2E discussion similar to yours.
