#define SEGMENT_BUFFER_SIZE 6
// Initialize and setup the stepper motor subsystem
// Enable steppers, but cycle does not start unless called by motion control or runtime command.
// Immediately disables steppers
// Generate the step and direction port invert masks.
// Reset the stepper subsystem variables
// Reloads step segment buffer. Called continuously by runtime execution system.
// Called by planner_recalculate() when the executing block is updated by the new plan.
// Called by runtime status reporting if realtime rate reporting is enabled in config.h.
