The DTIF bit in DMDR is set to 1 after the total transfer size of transfers is completed. When both
the DTIF and DTIE bits in DMDR are set to 1, a transfer end interrupt by the transfer counter is
requested to the CPU or DTC.
The DTIF bit is set to 1 when the ACT bit in DMDR is cleared to 0 to stop a transfer after the bus
cycle is completed.
The DTIF bit is automatically cleared to 0 and a transfer request is cleared if the transfer is
resumed by setting the DTE bit to 1 during interrupt handling.
For details on interrupts, see section 9.8, Interrupt Sources.
9.5.8
The channels of the DMAC are given following priority levels: channel 0 > channel 1. Table 9.6
shows the priority levels among the DMAC channels.
Table 9.6
The channel having highest priority other than the channel being transferred is selected when a
transfer is requested from other channels. The selected channel starts the transfer after the channel
being transferred releases the bus. At this time, when a bus master other than the DMAC requests
the bus, the cycle for the bus master is inserted.
In a burst transfer or a block transfer, channels are not switched.
