Section 6 Instruction Descriptions
The six functions noted below are used for DSR register updating. The DC bit in the DSR register
is updated in accordance with the operation results of the DSP operation instructions and the
directions of the status selection bit (CS). The other bits in the DSR register are updated in
accordance with the operation results of the DSP operation instructions only.
