Programming the channel field to channel 63 denotes the end of the
queue. Channels 60 to 62 are special internal channels. When one of
the special channels is selected, the sampling amplifier is not used.
The value of V
Programming any input sample time other than two has no benefit for
the special internal channels except to lengthen the overall
conversion time.
