Section 6 Instruction Descriptions
3. Multiplier Input/Output
The multiplier input/output is defined based on the union named DSP_MUL_Set noted below.
This union is composed of four longwords. One longword each is allocated for the two inputs, but
only the upper 16 bits of both of these (usi [0], usi [2]) are used. Two longwords including guard
bit usage (dst, dstg) correspond to the outputs.
The multiplier input/output names are defined as follows, using the union DSP_MUL_Set noted
above.
