3.3 Control Module Changes

There are minimal changes in the control modules between the F28003x and F28P55x devices. There are significantly more ePWM modules on the F28P55x. The SDFM module and the HRCAP module are removed from the F28P55x device. Table 3-2 shows the module instances differences which should be considered when migrating applications between F28003x and F28P55x.
