Single conversions on two ADC channels, CH0 with gain
Single conversions on two ADC channels, CH1 with gain
first conversion has started. In this example both conversions replaced at the same time, but
conversion on ADC Channel 1(CH1) does not start until the ADC samples and performs conver-
sion on MSB on Channel 0 (CH0).

Figure 28-16 on page 362
nels where ADC Channel 0 uses the gain stage. As the gain stage introduce one addition cycle
for the gain sample and amplify, the sample for ADC Channel 1 is also delayed one ADC clock
cycle, until the ADC sample and MSB conversion is done for ADC Channel 0.
