[NRF5340] UARTE speed up to 3Mbps (max)

[NRF5340] UARTE speed up to 3Mbps (max)https://devzone.nordicsemi.com/f/nordic-q-a/73977/nrf5340-uarte-speed-up-to-3mbps-maxIn our application the prospective Nordic NRF5340 MCU is to communicate with another MCU at the maximum 3Mbps. Can this speed ( 3Mbps) be achieved on NRF5340?

You have to use SPI for higher speeds <a href="https://infocenter.nordicsemi.com/topic/ps_nrf5340/spim.html#unique_1244825778">https://infocenter.nordicsemi.com/topic/ps_nrf5340/spim.html#unique_1244825778</a></p> <p>High speed clocks needs the GPIO to be set in high drive in order to toggle fast enough.</p> <p></p> <p>best regards,</p> <p>Ketil Aas-Johansen</p><div style="clear:both;"></div>
