Contribution description
When the motor driver mode is set to
MOTOR_DRIVER_2_DIRS, the states of theDIR0andDIR1pins encode both the rotation direction and whether the motor should brake."Removing" the brakes causes both pins to be set to the inverse of the braking state. So, if the driver is configured to brake high, both pins will be set low, and vice versa. Most H-bridges will break both in the low and high state.
I also adjusted the phrasing in the documentation a bit.
