Hello, All! I just got DSP56F807EVM.. I have some questions.. 1. From where I can download full dsp56000 assembler guide? 2. How can I read (view in debug watch) quad decoder (or any) register contents? QDec -some decoder register address . asm {move X:QDec, N } but I can't view N in debugger watch, only C variables are available. need any examples.. pls. Thanks for your help. With best regards, Andrew Shelkovenko. http://home.omni.spb.ru/mira/rqsr |

All of the documemtation is available from Motorola: http://e-www.motorola.com/webapp/sps/library/documentationlist.jsp? rootNodeIdz6wYqRXz&nodeIdz6wYqRXz&Device=All&DocTypeKeyKsgj8 q&Set=1&Results% You want: DSP56F801-7UM.pdf for all of the perhipheral information, and DSP56800FM.pdf for the core and instruction set information. The users manual for the EVM is also there. All of the peripheral registers are memory mapped in X-memory. You should be able single step in your debugger or simulator, and watch them update. At least that's true in the Code Warrior IDE I'm using.

The only documentation that has the assembly instructions is the DSP56800 Family Manual which can be found at: http://e-www.motorola.com/webapp/sps/library/documentationlist.jsp? rootNodeId&nodeId27956292&Device=All&DocTypeKeyKsfwlk The document is called DSP56800 16-Bit Digital Signal Processor Family Manual and you are interested in Appendix A entitled Instruction Set Details. If you are using CodeWarrior there is a option called View Registers that will let you see the registers. Also if you know the address location of a particular register you can also view that memory location to see the contents.

Andrew, I finally found the text file which a kind person sent me - but I've lost his name. I think he was "David D" of "beanfranks" at Yahoo.com. Thank you, David, if I'm right. He interprets the opcode bit patterns in 568xx ASM. If anyone would like this file (56KByte), let me know and I'll forward it without cluttering everyone's Inbox.
