| Question:                                                         |
| As given on page 7-23 of the DSP56000 User's Manual under section |
| 7.3.13.2, step number 4, it is possible to access the DSP's ICR,  |
| ISR and RXH:RXM:RXL by the Host processor once DMA has been       |
| enabled.  Can the CVR (Command Vector Register) also be accessed  |
| once DMA has been enabled?                                        |

Answer: Yes.
Any of the Host Port registers, except TXH:TXM:TXL, can be read
or written by the Host processor in this situation. 

When in DMA mode, the Host processor can access any register not
being used for the DMA transfer.  The two types of accesses do
not interfere because DMA mode access is controlled by HREQ and
HACK pins.  Ordinary Host port register access is controlled by
HEN, HR/W and HA2-HA0 pins.
