Hi Jay,

Yes, you can select both as 0x0 but the demerit is the UVLO for 5V will be way lower now (2.45), hence the GDIC will function even when VCC1 fluctuates and goes as low as 2.5V for a 5V VCC1 (given everything else is powered up and working well). If that is something the customer is okay with, they can set both as 0x0.

Best,
Pratik
