Conversion rate control bits modify the time interval for conversion of the channels
enabled. The channels enabled are converted sequentially then standby mode
enabled for the remainder of the time interval.

2.3.3 Channel Conversion Enable
When a conversion is disabled for a particular channel it is skipped. The continuous conversion rate is effected all other conversion
rates are not effected as extra standby time is inserted in order to compensate. See Conversion Rate Register description.
