8.5
There are three transfer modes: normal, repeat, and block transfer modes. Since transfer
information is in the data area, it is possible to transfer data over any required number of channels.
When activated, the DTC reads transfer information stored in the data are and transfers data
according to the transfer information. After the data transfer is complete, it writes updated transfer
information back to the data area.
The DTC specifies the source address and destination address in SAR and DAR, respectively.
After a transfer, SAR and DAR are incremented, decremented, or fixed independently.
Table 8.3 shows the DTC transfer modes.
Table 8.3
Notes: 1. Either source or destination is specified to repeat area.
Setting the CHNE bit in MRB to 1 makes it possible to perform a number of transfers with a
single activation (chain transfer). Setting the CHNS bit in MRB to 1 can also be made to have
chain transfer performed only when the transfer counter value is 0.
Figure 8.4 shows a flowchart of DTC operation, and table 8.4 summarizes the conditions for DTC
transfers including chain transfer (combinations for performing the second and third transfers are
omitted).
