18.4 Transfer Targets
18.5 Transfer Modes
request, transfer is performed again once. This operation continues until a terminal count occurs.
DMA request always takes precedence.
generated in a transfer cycle, DMA transfer of the channel with the lower priority is executed after the bus is released
to the CPU (the new transfer request of the same channel is ignored in the transfer cycle).
Table 18-2 shows the relationship between the transfer targets (√: Transfer enabled, ×: Transfer disabled).
Caution The operation is not guaranteed for combinations of transfer destination and source marked with
Single transfer is supported as the transfer mode.
In single transfer mode, the bus is released at each byte/halfword transfer. If there is a subsequent DMA transfer
When the DMAC has released the bus, if another higher priority DMA transfer request is issued, the higher priority
If a new transfer request of the same channel and a transfer request of another channel with a lower priority are
“×” in Table 18-2.
