mode, CH0 and CH1 without gain and CH2 and CH3 with gain. When set up in free running
mode a ADC channel will continuously sample and do new conversions. In this example all ADC
channels are triggered at the same time, and each ADC channel sample and start converting as
soon as the previous ADC channel is done with it sample and MSB conversion. After four ADC
clock cycles all ADC channels have done the first sample and started the first conversion, and
each ADC channels can then do the sample conversion start for the second conversions. After 8
(for 12-bit mode) ADC clock cycles the first conversion is done for ADC Channel 0, and the
results for the rest of the ADC Channels is available in the next ADC clock cycles. After the next
clock cycle (in cycle 10) the result from the second ADC Channel is done and available and so
on. In this mode up to 8 conversions are ongoing at the same time.
