Hello:
I am starting to work with assembly for the c5000 (5009).
I am working on 2 buffers in the following way:
.....
RPT CSR
MACM *AR0+, *AR1+, AC0
.....

The addresses are passed as C function parameters with AR0 and AR1.
The problem is that the buffers that I am pointing with AR0 and AR1 are 
in an external SDRAM (addresses are longer than 16 bit), so the MAC wont 
work.
I understand that I can address such a buffer with XAR0 and XAR1, but 
how can I do that with teh MAC instruction??

Thanks for the help.
