5.1 Operation

The SD.LINK module transfers data in set area to a remote CPU (or LPU).
CPU-0 (or LPU-0)
CPU-0 (or LPU-0)
Figure 5-1 and Figure 5-2 show the memory transfer operations of each CPU or LPU.
① CPU-0 (or LPU-0) transfers area A to CPU-1 and CPU-2 (or LPU-1 and LPU-2).
② CPU-1 (or LPU-1) transfers area B to CPU-0 and CPU-2 (or LPU-0 and LPU-2).
③ CPU-2 (or LPU-2) transfers area C to CPU-0 and CPU-1 (or LPU-0 and LPU-1).
④ By this time, areas A to C have been shared by CPU-0 to CPU-2 (or LPU-0 to LPU-2).
Then, the flow returns to ① to iterate the sharing operation.
For a mixed connection of S10mini CPU units and S10V LPU units, see "4.6.7
