DRA821U: VDDSHV2 power sequencing when 1.8V

Tool/software:

Hello,

I need to used a mixed power plan for pins VDDSHV0 @3.3V / VDDSHV2 @1.8V / VDDSHV5 @3.3V.

The PMIC sequences the 3.3V first then (2 milliseconds later) the 1.8V rail.

Is it permissible to power the VDDSHV2 @1.8V using the delayed PMIC rail?

NOTE: I do not intend to use any retention modes.

Thanks,

Steve
