Hello,
There are some power supply pins, VSYS, VBUS, VCONN, VDDD, VDDIO in CCG3.
Could you tell me the power up sequence for those pins if those pins is used for input?
Best regards,

Hi Takeshi,
There are no critical power sequence base for those power pins. You could power anyone of them first and then after others. For Best practice, recommend you VSYS first and then others. Since this is follow firmware default setting. If your design cannot meet this, it is fine.
Best Regards,
Lisa
