Section 7 DMA Controller (DMAC)
In repeat mode, operation continues until the DTE bit in DMABCRL is cleared. To end the
transfer operation, therefore, the DTE bit should be cleared to 0. A transfer end interrupt request is
not sent to the CPU or DTC. By setting the DTE bit to 1 again after it has been cleared, the
operation can be restarted from the transfer after that terminated when the DTE bit was cleared.
Figure 7.7 illustrates operation in repeat mode.
Transfer requests (activation sources) consist of A/D converter conversion end interrupts, external
requests, SCI transmission complete and reception complete interrupts, and TPU channel 0 to 5
compare match/input capture A interrupts. External requests can only be specified for channel B.
Figure 7.8 shows an example of the setting procedure for repeat mode.
