Introduction This document describes the known exceptions to the functional specifications for the TMS320C6455/54 digital signal processors; see the TMS320C6455 Fixed-Point Digital Signal Processor data manual (literature number SPRS276) and the TMS320C6454 Fixed-Point Digital Signal Processor data manual (literature number SPRS311). For additional information, see the TMS320C6000 DSP Peripherals Overview Reference Guide (literature number SPRU190). The advisory numbers in the document are not sequential. Some advisory numbers have been moved to the next revision. When items are moved, the remaining advisory numbers are not resequenced. This document also contains "Usage Notes." Usage Notes highlight and describe particular situations where the device's behavior may not match presumed or documented behavior. This may include behaviors that affect device performance or functional correctness. These notes will be incorporated into future documentation updates for the device (such as the device-specific data manual), and the behaviors they describe will not be altered in future silicon revisions.
