Browse Source 
set_force_level can only set the generator level before the deadtime module.

* @note The force level will be applied to the generator immediately, regardless any other events that would change the generator's behaviour.
* @note If the `hold_on` is true, the force level will retain forever, until user removes the force level by setting the force level to `-1`.
* @note If the `hold_on` is false, the force level can be overridden by the next event action.
* @note The force level set by this function can be inverted by GPIO matrix or dead-time module. So the level set here doesn't equal to the final output level.
