16 DIAG Outputs  
16.1 STEP/DIR Mode  
Operation with an external motion controller often requires quick reaction to certain states of the  
stepper motor driver. Therefore, the DIAG outputs supply a configurable set of different real time  
information complementing the STEP/DIR interface.  
Both, the information available at DIAG0 and DIAG1 can be selected as well as the type of output  
(low active open drain default setting, or high active push-pull). In order to determine a reset of the  
driver, DIAG0 always shows a power-on reset condition by pulling low during a reset condition.  
Figure 16.1 shows the available signals and control bits.

Figure 16.1 DIAG outputs in STEP/DIR mode  
The stall output signal allows stallGuard2 to be handled by the external motion controller like a stop  
switch. The index output signals the microstep counter zero position, to allow the application to  
reference the drive to a certain current pattern. Chopper on-state shows the on-state of both coil  
choppers (alternating) when working in spreadCycle or constant off time in order to determine the  
duty cycle. The dcStep skipped information is an alternative way to find out when dcStep runs with a  
velocity below the step velocity. It toggles with each step not taken by the sequencer.  
Attention  
The duration of the index pulse corresponds to the duration of the microstep. When working without  
interpolation at less than 256 microsteps, the index time goes down to two CLK clock cycles.  
16.2 Motion Controller Mode  
In motion controller mode, the DIAG outputs deliver a position compare signal to allow exact  
triggering of external logic, and an interrupt signal in order to trigger software to certain conditions  
within the motion ramp. Either an open drain (active low) output signal can be chosen (default), or an  
active high push-pull output signal. When using the open drain output, an external pull up resistor in  
the range 4.7kΩ to 33kΩ is required. DIAG0 also becomes driven low upon a reset condition. However
