### 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
finalize_config crc=0

On AVR platforms, the highest achievable step rate is with just one
stepper stepping. On the STM32F103, Arduino Zero, and Due, the highest
step rate is with two simultaneous steppers stepping. On the PRU,
SAM4S8C, SAM4E8E, and LPC176x the highest step rate is with three
simultaneous steppers.
