Hi Milorad, You don't need to provide a continuous clock in autonomous mode. Only the first start of the conversion needs to be provided by the controller. You can configure the device to change between channel 0 and channel 1 automatically by enabling both channels for auto-sequencing (AUTO_SEQ_CHEN register) and then starting the sequence (START_SEQUENCE Register). This will allow you to monitor both channels autonomously by setting the ALERT thresholds in the digital window comparator registers (DWC_HTH_CHx and DWC_LTH_CHx registers). Regards, Joel
