Product status(2)
(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.
(2) See Section 5.1, Device and Development Support Tool Nomenclature, for descriptions of device stages.
