3.9 Analog Multiplexing Changes

outlines the differences and similarities that exist in the analog mux between F280015x and F28P55x for the 80-Pin PN/PNA and the F280013x/15x and F28P55x for the 64-Pin PM packages. 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
