I’m posting the following requirement related to the RTC_Vss pin connection.
In datasheet I can see the RTC power module is isolated.
And in the Hardware Checklist :
I can see that RTC_Vss connection to Vss is only mentioned when pin is not used.
Can RTC_Vss be connected to the general VSS or does it have to be connected to a dedicated Vss reference?
If RTC is used in your design, the recommendation is to follow the datasheet and not tie RTC_VSS to board ground.
