Section 11 EXDMA Controller (EXDMAC)
Figure 11.10 shows an example of EXDMA transfer timing in block transfer mode. The transfer
conditions are as follows:
Address mode: Single address mode
Data access size: In bytes
One block size: 3 bytes
Figure 11.11 shows the block transfer mode operation in single address mode and figure 11.12
shows the block transfer mode operation in dual address mode.
