⁷ High bit rates may require GPIOs to be set as High Drive or Extra High Drive, see GPIO chapter for more details.

⁸ High bit rates may require GPIOs to be set as High Drive or Extra High Drive, see GPIO chapter for more details.

⁹ For SPIM00 using GPIO port P2.

¹⁰ At 25pF load, including GPIO pin capacitance, see GPIO spec.
