3.1 Interfaces Summary
3.2 External Interface Multiplexing
Most general purpose IO ports of the device (PIOA, PIOB and PIOC) hav e been assigned
multiple functions, selected under software control and external configuration pin setup. Up to
two alternative functions and general purpose IO may be assigned to each external pin. The
selection among the various choices is described in Figure 3-2.
3.2.1 CO2128/CO2144 Configuration Options
Eight different configuration options are possible by selecting the functions available per pin
cluster. Figure 3-2 shows the pin cluster options.
