4.3 Control Module Changes

There are changes in the control modules between the F28P65x and F29H85x devices. The biggest changes come from the EPWM and ECAP on the F29H85x device. Table 4-10 shows the module instances differences that should be considered when migrating applications between F28P65x and F29H85x.
