Hi Choi,

You can check this doc - C2000 Compiler Users Guide : http://www.ti.com/lit/ug/spru514h/spru514h.pdf
This covers all C and assembly details.

Gautam

Hi,

You can use the indirect branch instruction "LB *XAR7". So you would do this

__asm(" MOVW  DP, #_vari   \
        MOVL  XAR7, @_vari \
        LB    *XAR7");

In addition to the doc Gautam pointed out you can also refer to SPRU430E for a description of the indirect branch
