I have already used it with up to 22MHz, but since that&#39;s out of spec, I guess I should go back down to 8MHz.

This is listed in the <a href="https://docs.nordicsemi.com/bundle/ps_nrf54L15/page/_tmp/nrf54l15/autodita/SPIS/parameters.interface.html">SPIS slave interface electrical specifications</a>. (For other parameters, see <a href="https://docs.nordicsemi.com/bundle/ps_nrf54L15/page/_tmp/nrf54l15/autodita/SPIS/parameters.elec_spec.html">Serial Peripheral Interface Slave (SPIS) timing specifications</a>),</p><div style="clear:both;"></div>
