Description. This method sums the values stored in any two given registers and stores the result in a third register.
int add_reg ( Uint32 RegDest, Uint32 RegSource1, Uint32 RegSource2 )
This method takes three parameters. The first of these is the
register in which the result is to be stored
RegDest). The second and third
RegSource2) are the registers whose
values are to be summed.
It is possible to re-use for storing the result one of the
registers whose values are summed; that is,
RegDest can be the same as
0 on success,
