	Properties
	Control Method
Controls how the motor is controlled. On/Off requires output pins PWM requires a hardware PWM channel H-Bridge requires a hardware H-Bridge channel
	Bridge Type
	Enable Method
Decides how the motor outputs are enabled.
	Channel
PWM Channel selector
	Alt Pin Enable
Alternative Pin Enable (if available on target device)
	Port
	Remap Pin
	Period Register
PWM Period Register value
	Prescaler Divide
Prescaler Divider value
	PWM Timer
Timer associated with PWM to drive the output. Warning - All PWM channels linked to the same timer will share the same period and prescaler settings.
	Frequency (KHz)

Number of bits assigned to the falling edge dead band counter. Auto populated based on selected target chip.
	Rising Count
Number of cycles to wait after a falling edge and before a rising edge.
	Falling Count
Number of cycles to wait after a rising edge and before a falling edge.
	Speed
Speed of the motor when turned on. Positive speed -> Counter-clockwsie Negative speed -> Clockwise
