(1) A type change represents a major functional feature difference in a peripheral module. Within a peripheral type, there may be minor
differences between devices that do not affect the basic functionality of the module. These device-specific differences are listed in the
TMS320x28xx, 28xxx DSP Peripheral Reference Guide (literature number SPRU566) and in the peripheral reference guides.
