Flexible full step and polarity set up to return the pointer to its reset position in clockwise or
counter clockwise direction.
Integrator/Sigma Delta converter circuit to measure the induced voltage by the back EMF of
unpowered coil during full step (only one of the two motor coils is powered) operation.
16-Bit Down Counter to monitor blanking and integration time to support stepper motors with
different gear ratios.
16-Bit accumulator register to read integration value, compare to a threshold at the end of
integration time, and decide if the motor is stalled under this value or moving above this value.
