7.3.1
When activated, the DTC reads register information that is already stored in memory and transfers
data on the basis of that register information. After the data transfer, it writes updated register
information back to memory. Pre-storage of register information in memory makes it possible to
transfer data over any required number of channels. Setting the CHNE bit to 1 makes it possible to
perform a number of transfers with a single activation.
Figure 7.2 shows a flowchart of DTC operation.
