*) In the operating modes with 3-wire configuration or with differential inputs,
two adjacent analog inputs belong together (e.g. the channels 0 and 1). In
these cases, both channels are configured in the desired operating mode. The
lower address must be the even address (channel 0). The next higher address
must be the odd address (channel 1). The converted analog value is available
at the higher address (channel 1).
