4.6.3 Pinout and Addressing of the Analog I/Os
An analog channel is always addressed word by word.
Figure 1-16 shows which channel addresses are obtained. You will see that, in the

of the analog I/Os, the analog input channels and the analog output channel are
addressed as of the same address, the start address.
