Section 6 Instruction Descriptions
6.2.2
Single data transfers are instructions that load to and store from the DSP register. They are like
system register load and store instructions. Data transfers between the DSP register and memory
use the main buses. Like CPU core instructions, data accesses can create access contention with
instruction memory accesses.
Single data transfers can use either word or longword data. Figure 6.16 shows the load and store
operations in single data transfers.
