3.9 Analog Multiplexing Changes

Table 3-19 and Table 3-20 outline the differences and similarities that exist in the analog mux between F28003x and F28004x for the 100-Pin PZ and 64-Pin PM respectively. The legend for the tables is Table 3-18. The main changes are the absence of the PGA and the reduction of the number of CMPSS modules in F28003x from the seven that exist in F28004x to four.
