Interface definitions

M1 and M2 are connected to the right motor, while M3 and M4 are connected to the left motor. PWMA and PWMB are output enable pins, active high enable. When they are driven to High level, the PWM pulse will be outputted from M1, M2, M3 and M4, so as to control the speed of the robot.
