Section 7 DMA Controller (DMAC)
7.3.6
The DMAC can activate the DTC with a transfer end interrupt, rewrite the channel on which the
transfer ended using a DTC chain transfer, and then reactivate the DTC. DMAWER applies
restrictions for changing all bits of DMACR, and specific bits for DMATCR and DMABCR for
the specific channel, to prevent inadvertent rewriting of registers other than those for the channel
concerned. The restrictions applied by DMAWER are valid for the DTC.
Figure 7.2 shows the transfer areas for activating the DTC with a channel 0A transfer end interrupt
request, and reactivating channel 0A. The address register and count register areas are set again
during the first DTC transfer, then the control register area is set again during the second DTC
