ADSP- 21489 DMA

Does anyone know if Internal memory to External memory (or viceversa) DMA is supported in the ADSP-21489 ?

I tried Internal to External and External to Internal DMA and it did not seem to work. Has anyone else tried this ?

For reference, on the ADSP-214xx SHARC Processor Hardware Reference, Figure A-11 DMACx Registers (page A-24), Bit 1 TRAN determines the DMA data direction for internal to internal transfers.
