AS5600-ASOT schematic

Hi, I’ve been using this chip in a 5v system, but now I have a different project that will be 3.3v. If I’m understanding the Datasheet correctly, I should be able to just make one tiny change to be able to use my existing pcb with this chip (the pcb mounts on the back of a NEMA17 stepper). here is my current schematic for a 5v system (see photo). and then looking at the Datasheet, it seems if I just jumper pins 1 and 2 on the AS5600 together, & remove the 1uf cap, I can change my Vcc from 5 volt to 3.3 volt? See figure 38 in the Datasheet. But I thought I’d ask, to be certain I underhand that Datasheet correctly. btw, I won’t be burning the chip’s memory slot.

Figure 13 on the datasheet also shows that setup.

Thanks! I missed figure 13, but it makes it clearer. That’s great, I won’t need to make a new pcb, then.
