Section 8 Data Transfer Controller (DTC)
8.5
Operation
Register information is stored in on-chip RAM. When activated, the DTC reads register
information in on-chip RAM and transfers data. After the data transfer, the DTC writes updated
register information back to on-chip RAM.
The pre-storage of register information in on-chip RAM makes it possible to transfer data over any
required number of channels. The transfer mode can be specified as normal, repeat, or block
transfer mode. Setting the CHNE bit in MRB to 1 makes it possible to perform a number of
transfers with a single activation source (chain transfer).
The 24-bit SAR designates the DTC transfer source address, and the 24-bit DAR designates the
transfer destination address. After each transfer, SAR and DAR are independently incremented,
decremented, or left fixed depending on its register information.
Figure 8.5 shows the flowchart of DTC operation.
