IWRL6432: Is it possible to use wakeup signal from two GPIOs at the same time?

Part Number: IWRL6432

Tool/software:

Hi team,

When we select LPDS wake up source, we can choose only one pin from GPIO or SYNC_IN (like below in SysConfig).

If customer want to use two GPIO, Can they get the Wakeup signal from two GPIOs at the same time?

And can we distinguish two GPIO sources?

*Customer will use two of the GPIO-WU_REQIN PINs at the same time.

Regards,

Lina

HI,

I don't think this is enabled by default. Can the customer use an OR gate to accomplish this?

Hello Nathan,

Thank you for the quick answer.
I suggested customer to use OR gate but, they want to implement the system with SW.

And following the E2E thread below. It seems possible to use two GPIO(REQIB) at the same time.

Could you check this thread too?

Lina

HI,

When you follow the instructions in that thread does it work? Perhaps it is enabled if you bypass sysconfig.

Hi Nate,

Customer decided to use a different wakeup source(UART) instead.

Thanks for your comments.
