This read-only bit indicates if the motor is at a steady speed or if it is
accelerating or declerating.
This read-only bit indicates the direction of the motor. It also indicates if the
motor is stopped.
This read-only bit indicates PWM output activity
This read-only bit indicates the state of the RBRAKE output pin
