Section 3 DSP Operating Unit
Table 3.15 Source Register in DSP Operations
Note:
The DSP unit incorporates one control register and DSP status register (DSR). The DSR register
stores the DSP data operation result (zero, negative, others). The DSP register also has the DC bit
whose function is similar to the T bit of the CPU register. The DC bit functions as status flag.
Conditional DSP data operations are controlled based on the DC bit. These operation control
affects only the DSP unit instructions. In other words, these operations control affects only the
DSP registers and does not affect address register update and CPU instructions such as load and
store instructions. A condition to be reflected on the DC bit should be specified to the DC status
selection bits (CS[2:0]).
The unconditional DSP type data instructions other than PMULS, MOVX, MOVY, and MOVS
change the condition flag and DC bit. However, the CPU instructions including the MAC
instruction do not modify the DC bit. In addition, conditional DSP instructions do not modify the
DSR.
