3.9 Analog Multiplexing Changes

Table 3-14 outlines the differences and similarities that exist in the analog mux between F28003x and F28P55x for the 80-Pin PNA and 64-Pin PM packages. Table 3-15 outlines the differences and similarities that exist in the analog mux between F28003x and F28P55x for the 100 PZ package. The legend for the table is Table 3-13. The main change is the addition of ADCD, ADCE and the PGA. There are also many more AGPIOs on the F28P55x
