Register information is stored in an on-chip RAM. When activated, the DTC reads register
information in an on-chip RAM and transfers data. After the data transfer, it writes updated
register information back to the RAM.
Pre-storage of register information in the RAM makes it possible to transfer data over any required
number of channels. The transfer mode can be specified as normal, repeat, and block transfer
mode. Setting the CHNE bit to 1 makes it possible to perform a number of transfers with a single
activation source (chain transfer).
