i.mx7 without internal RTC but SNVS tamper

Hello community!

 

Quick question on the possibility of the following:

Both tamper detection and RTC are needed. Based on i.MX7/PF3000 RTC Backup Power an external RTC will be used. Tamper and internal RTC are both powered by SNVS power domain.

 

Is it possible to disable the internal RTC while still using tamper detection?
May the RTC Oscillator/Pins be left unconnected if an externl RTC is used? Does this have any effect on this power domain setup?

 

Thanks and regards,
Lars
