“Enter.”
⚠️
Do not forget to click

Ensure that the VCC of the communication interface is fully discharged.
To reset EVB:
For offline mode, ensure that the EBV VCC is fully discharged. For online mode, ensure that the EVB VCC is fully
discharged and the bus bulk capacitor is discharged below 10V.
VCC fully discharged:
VCC discharged below 2V. The discharge time may vary with different application designs.
