Is it mandatory to connect VDDSHV5 to a supply voltage or can it be left floating if IO group 5 is not used?

The recommendation is to connect a valid power supply to VDDSHV5.

The schematic of the eval board in pdf file "PROC135A" shows a level translator between AM62A and PMIC (page 33). Why is it used? Datasheet of TPS6593 reads that VIL(DIG) is 0.54 V and VIH(DIG) is 1.26 V for the used IO pin. This should be fine with 1.8 V output of AM62A on "MCU_ERRORn". Do you have further information on this and a recommendation?

Are you checking if the level shifter can be removed?

The SK is a generic design designed parallel to the SOC and PMIC design.

Customer are allowed/encouraged to review and do the required optimization preferably after testing.
