AM625: PMIC_LPM_EN0 is not toggling when entering sleep mode.

Tool/software:

We are monitoring the PMIC_LPM_EN0 pin from the AM62x using processor-sdk 10.0.

The PMIC_LPM_EN0 pin is connected to the TPS65219 MODE pin and has a 4.7k pullup on it.

During normal operation, the value on PMIC_LPM_EN0 is '1'.

When we issue the sleep command:

rtc -wake 30 -m mem

the state of the PMIC_LPM_EN0 is expected to change to '0', but it does not.  It remains high.  Is this expected behavior?  

We can't find much documentation about how this pin is controlled in the TRM or the datasheet.

This is related to this E2E post on the PMIC:

we were asked to check with the processor group about this pin.

Thanks,
