Section 8 DMA Controller (DMAC)
restored in accordance with the values of the DTSZ and DTID bits in DMACR. The MAR
restoration operation is as shown below.
The same value should be set in ETCRH and ETCRL.
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 8.7 illustrates operation in repeat mode.
