(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)

An integer divide ratio must be maintained between the C28x and M3 clock frequencies; thus, when the C28x is configured to run at maximum frequency of 150 MHz, the fastest allowable

frequency for the M3 will be 75 MHz.
