Reload function: The value that was specified in the source address register can be
automatically reloaded every 4 DMA transfers. This function is only valid in channel 2.
Three types of Transfer requests
Selectable bus modes: Cycle-steal mode or burst mode
Selectable channel priority levels
Interrupt request: An interrupt request can be generated to the CPU after transfers end by the
specified counts.
External request: From two DREQ pins (channels 0 and 1 only). DREQ can be detected
either by the falling edge or by the low level.
On-chip module request: Requests from on-chip peripheral modules such as serial
communications interface (SCIF), A/D converter (A/D), and a timer (CMT). This request
can be accepted in all the channels.
Auto request: The transfer request is generated automatically within the DMAC.
Fixed mode: The channel priority is fixed.
Round-robin mode: The priority of the channel in which the execution request was
accepted is made the lowest.
