When USB0 and USB1 are not used or USB0 or USB1 is not used, the interface signals and the USB supplies have specific connectivity requirements.
For connecting the interface signals and USB supply pins, refer the Pin Connectivity Requirements section of the device-specific data sheet.
It is recommended to connect the USB supplies (VDDA_CORE_USB, VDDA_1P8_USB, and VDDA_3P3_USB) to VSS through separate 0 Ω resistors.
In case USB0 or USB1 are used for future expansion, connect the signals (USBn_DM, USBn_DP, USBn_RCALIB and USBn_VBUS) with the shortest possible traces and connect at test points or connectors. Additionally, it is recommended to provide provision to connect the required USB supplies.
