When the bit is not 0, the random PWM function works. The larger the value, the wider the fluctuation range and the flatter the noise spectrum. It should be noted that after opening the random carrier, the electromagnetic noise of the motor will not necessarily be reduced, and the actual noise perception varies from person to person.
