### SAMD51 step rate benchmark ###
The following configuration sequence is used on the SAMD51:
```
allocate_oids count=3
config_stepper oid=0 step_pin=PA22 dir_pin=PA20 min_stop_interval=0 invert_step=0
config_stepper oid=1 step_pin=PA22 dir_pin=PA21 min_stop_interval=0 invert_step=0
config_stepper oid=2 step_pin=PA22 dir_pin=PA19 min_stop_interval=0 invert_step=0
