S32K146 Wakeup by uart

hongmei — Mon, 22 Jul 2024 10:04:18 GMT

Hello,

I am using S32K146 for development now. And I have a question about mcu wake up by uart.

Question 1:

Does S32K146 support wake up by uart in standby state?

Question 2:

If S32K146 supports wake up by uart, how to config uart in S32 Design Studio?

Is there any sample than I can refer to?

Best Regards,

Thanks

Hi@hongmei

Question 1:Does S32K146 support wake up by uart in standby state?

yes, Lpuart can be wake up from S32K1's low power mode.

you can read the datasheet for more detail.

Question 2:If S32K146 supports wake up by uart, how to config uart in S32 Design Studio?

Is there any sample than I can refer to?

I checked and found that the SDK we provide does not support "IDLE " interrupt configurations. You need to manually configure and modify them. I found some similar answers that may be helpful to you.
