dsk5510 dsk1_app.pjt DMA query - ocku...@gmail.com - Feb 4 14:24:00 2006



Hi all,
    I am Omkar. I am working on dsk5510 by spectrum digital. I am not getting the connection
between the DMA Block End interrupt and the hardware interrupt HWI 9 in the example
dsk1_app.pjt provided by them. Can anybody pls help me in understanding these? Perticularly my
query is, whether the DMA channel 1 Block End interrupt has an in built connection to HWI 9 or
in other words, HWI 9 is a dedicated interrupt to DMA channel 1 Block End event? Pls help me in
this issue. Also pls let me know if there is any reading material available which clarifies
this. Because I have gone through the CPU reference guide and Peripheral reference guide for
c5510.

Very sorry if the issue has been discussed here. I was unable to find anything simillar.

regards,
Omkar.

Omkar, 
you might have a look at the examples of code composer. There are 4 code 
examplese. It's at least a good point to start from.
