https://devzone.nordicsemi.com/f/nordic-q-a/122803/nrf5340-i2c-twi-2khz-frequencyHi - I&#39;d like to set the i2c to clock in at no more than 2 khz. Are there FREQUENCY register settings that would work for this. In addition, is there a reference as to how the FREQUENCY register is calculated for a desired i2c clock rate?

You can experiment lower values but it is not guaranteed or tested to work with other numbers than those documented.</p> <p><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1751959154036v1.png" alt=" " /></p><div style="clear:both;"></div>
