This article details a method and system for driving digital Input/Output (IO) signals in synchronization with specific events. In the proposed implementation, digital direction control signals are synchronized to a PWM synthesized sine wave such that direction control changes only occur at zero volt crossings to mitigate electrical disturbances.
