Higher current support: When using the EVM with
the external power adapter, the 5V supply is provided by the external power adapter.
For most use cases, this external power supply option is not used and power is
derived from the USB interface.
Note: After the 5V power supply is provided to the EVM, TI recommends pressing
the NRST switch one time to verify for a reliable boot-up state.
Note: All digital IO pins of the device (except NRESET) are not fail safe.
Therefore, care needs to be taken that the digital
IO pins are not driven externally without the VIO
supply being present to the device.
