C2xLP Migration Guidelines
The C28x DSP is source-code compatible with C2xLP DSP based devices.
The C28x DSP assembler accepts all C2xLP mnemonics with the exception
of a few instructions. This chapter provides guidelines for C2xLP code migra-
tion to a C28x device. C2xLP refers to the CPU used in all TMS320C24x,
TMS320C24xx, and TMS320C20x DSP devices.
