Howto reset I2C controller for 52840

Hi,

Working on a product with a couple to sensors with i2c communication. Are normally able read values from the sensors, but sometimes the i2c bus seem to be down. No more read/write operation succeeds.

We are using a pre-production version of the Nordic 52840. Are there any known issues regarding i2c for the pre-production devices?

How do I reset the i2c controller to see if this is the reason for hanging the i2c bus?

Thanks,

   Henrik
