3.2 Communication Module Changes

Communication module changes between the F2838x and F28P65x devices affect the number of modules and migration of CAN, CAN-FD, USB and Ethercat from CM side of F2838x to C28x on F28P65x. Module functionality is maintained for both devices. C2000Ware examples and driverlib covers the software migration of the communications modules that are controlled by CM on F2838x and moving to C28 on F28P65x. Table 3-1 shows the module instances and differences which should be considered when migrating applications between F2838x and F28P65x.
