I want to check for VDD_SNVS_IN using a coin battery.

During normal operation, VDD_SNVS_IN is the operating range is 2.9V ~ 3.3V.

- i.MX 6Solo/6DualLite Applications Processors for Consumer Products, Rev. 5 4.1.3 Operating Ranges

 

As an example, it shows the discharge characteristic graph of the ML621.

Immediately, coin battery is reduced to about 2.5V.

In addition, less than the operating range and supplies using the PMIC (MMPFxxxx).

If you want to back up the RTC in the Coin Cell Mode, operating  range of VDD_SNVS_IN will be 2.9V ~ 3.3V?
