Note 1: For all analog input pairs that do not have dedicated sample and hold circuits, the common sample and hold circuit
samples the input at the start of the first and second conversions. Therefore, the samples are sequential, not
simultaneous.
2: For all analog input pairs that have dedicated sample and hold circuits, the common sample and hold circuit samples
the input at the start of the first conversion so that both samples (odd and even) are near simultaneous.
