how to access a continue io space in tms320vc5402?

Started by Unknown May 5, 2008
i have a 2k x 8bit dpram in 5402's io space,now my
problem is how to access the 2k io space continue in
accembly.
read through the user guide of c5x instruction, it
seemed that the io space can only be access by a
single address, ex:
port( PA) = Smem

port(7h) = @OUTDAT ; OUTDAT .equ 07h
the PA is a immediatly value.

how can i access a continue io address?
thanks!
