4.2 Communication Module Changes

Communication module changes between the F28P65x and F29H85x devices affect the number of modules and migration. Module functionality is mostly maintained between both devices. Table 4-4 shows the module instances and major register differences which should be considered when migrating applications between F28P65x and F29H85x.
