59.2.8 USB Host/Device
| Signal Name | Recommended Pin Connection | Description | |
|---|---|---|---|
| VBG | 0.9 - 1.1V (1) (2) | Bias Voltage Reference for USB To reduce the noise on the VBG pin to a minimum, implement the layout considerations below: - Keep the VBG path as short as possible - Ensure a ground connection to GNDUTMI  VBG can be left unconnected if USB is not used. |
|
| HSDM / HSDP | Application dependent (1) (2) | USB High Speed Data Pulldown output at reset. |

Note:
- The following schematic shows an
example of USB High Speed host connection. For more information, refer to 38 USB High-Speed Interface (USBHS)
- The following schematic shows a
typical USB High Speed device connection: For more information, refer to 38 USB High-Speed Interface (USBHS).
Note: The values shown on the 22 kΩ and 15 kΩ resistors are only valid
with 3.3V supplied PIOs.
