7 Device Start-Up

After power-up, the device is kept in reset until the power has stabilized throughout the device. VDD and AVDD must have the same supply sequence, and must be connected together. VDDIOB must be available before the application uses features on pins supplied by VDDIOB.

Minimum and maximum VDD/AVDD/VDDIOB rise and falling rates can be found in the Power Supply Electrical Specifications from the "Electrical Characteristics" chapter.
