+### SAME70 step rate benchmark
+
+The following configuration sequence is used on the SAME70:
+```
+allocate_oids count=3
+config_stepper oid=0 step_pin=PC18 dir_pin=PB5 invert_step=-1 step_pulse_ticks=0
+config_stepper oid=1 step_pin=PC16 dir_pin=PD10 invert_step=-1 step_pulse_ticks=0
+config_stepper oid=2 step_pin=PC28 dir_pin=PA4 invert_step=-1 step_pulse_ticks=0
+finalize_config crc=0
+```
+
+The test was last run on commit `e3f1140d` with gcc version
+`arm-none-eabi-gcc (NixOS 10.3-2021.10) 10.3.1` on a SAME70Q20B
+micro-controller.
