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,
SAMD51, SAM4S8C, SAM4E8E, and LPC176x the highest step rate is with
three simultaneous steppers.

simultaneous steppers. On the SAMD51, the highest step rate is with
four simultaneous steppers.
