Fault Led; User Interface; Table 3. Modes And Gate Controls Available Vs Zvs Circuit Implementation - STMicroelectronics STEVAL-GLA001V1 User Manual

The firmware is able to manage ZVS circuit presence: according to the "zvs_hw" parameter value, some mode
operations may or may not be available. With the STEVAL-GLA001V1, the ZVS parameter is activated by default.
In case of firmware re-use with user-own design, ZVS function could be deactivated..
