*) 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).
