1. SignMagnitude PWM – For signmagnitude PWM operation, 2 control signals are used to            
control the speed and direction of the motor. PWM is feed to the PWM pin to control the                 

2. LockedAntiphase PWM – For lockedantiphase PWM operation, only 1 control signal is           
needed to control the speed and direction of the motor. PWM pin is connected to logic high                
while the DIR pin is being feed with the PWM signal. When the PWM signal has 50% duty                 
cycle, the motor stops running. If the PWM has less than 50% duty cycle, the motor will turn                 
