Hello Oleksiy Kasyan

Thank you for the query.

Please refer the TRM sectionas below.

I want to use pin L23 of the AM625 SoC as a WAKE signal input. But I can't find a clear answer to the following question:

The pin L23 is capable of waking up the SoC from every state except Partial I/O. or pin L23 is capable of waking up the SoC only from
Standby mode.

Please point me to the section of the TRM and the section where the above description is mentioned.

Hi Kallikuppa Sreenivasa

I know about "different" sleep modes.

I want to use pin L23 of the AM625 SoC as a WAKE signal.

And I'm not sure for which sleep mode this pin will work.

Hello Oleksiy Kasyan

Thank you.

Description. refer section 6.2.4 of the TRM.

Please elaborate your requirement.

Based on the 6.2.4 power modes section copied above, this pin could support standby power mode.
