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
basic functionality of the module. These device-specific differences are listed in the TMS320x28xx, 28xxx DSP Peripheral Reference Guide (literature number
) and in the
peripheral reference guides.
