nrf5340 i2c/TWI 2khz Frequency

[dstude]

Hi -

I'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?

Thanks,

Dave

The lowest frequency in TWI for nRF52 or nRF53 devices is 100Khz. You can experiment lower values but it is not guaranteed or tested to work with other numbers than those documented.
