(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) TMX samples will come with the ZEP designator. The designator will change to ZFE after TMS.
(3) Custom secure versions of these devices are available. See Section 3.2.9, Security, for more details.
