basically the same as in the double data transfer instructions described in section 2.6.3, Single and

Double Data Transfer for DSP Data Instructions, but has a special function in load instructions.

B-field data operation instructions are of three kinds: double data operation instructions,

conditional single data operation instructions, and unconditional single data operation instructions.

The formats of the DSP operation instructions are shown in table 2.30. The respective operands

are selected independently from the DSP registers. The correspondence between DSP operation

instruction operands and registers is shown in table 2.31.
