VDD_SNVS_IN voltage range

I have seen a contradiction in the i.MX 6DualPlus/6QuadPlus datasheet regarding VDD_SNVS_IN voltage range:

Table 6. Operating Ranges: 2.8V - 3.6V

Table 4. Absolute Maximum Ratings: -0.3V - 3.4V


Can you confirm that 3.6V is the absolute maximum of VDD_SNVS_IN for the i.MX 6DualPlus/6QuadPlus?

It this is correct, does this range (-0.3 - 3.6V) apply for all iMX6 family i.MX6Quad/Dual/DualLight/Solo?


I would like to short VDD_HIGH_IN VDD_SNVS_IN and connect both to a 3.3V supply.
Supply has a %5 tolerance which may end up at 3.465V. VDD_HIGH_IN can withstand this question is can VDD_SNVS_IN operate at 3.465V?
(Adding a schottky diode between VDD_HIGH_IN to VDD_SNVS_IN for lowering the voltage of VDD_SNVS_IN does not seem to be a solution since drop is negligible in the VSNVS max current of 275uA)


Thank you for your support
