Part Number: TDA4VM

Hello Champs,

There is MAIN domain GPIO and WKUP domain GPIO. Can MAIN domain GPIO be accessed by WKUP domain and vice versa?

Thanks

Hi Shine,

Yes, the MAIN domain and MCU/WKUP domain are connected to each other, so this is possible.

Hi Sumn,

Thank you very much for your great support.

Is there any way to make the GPIO only to be accessed by one domain at one time in hardware? Or it needs to controlled by software to avoid using the same GPIO by two systems?

Thanks
Regards,
Shine
