1.0 and 1.1
When a DMA block transfer is initiated by a sync event, if the same sync event occurs before
the last element of the block transfer has been completed, an event drop occurs and the
channel becomes disabled.
Ensure that the duration between the sync events is long enough to allow the block transfer to
complete. The DMA end-of-block interrupt can be used as an indicator.
1.0 and 1.1
The DMA controller does not support burst mode transfers with the EMIF as both the source
and the destination port.
Do not use burst mode for EMIF-to-EMIF transfers.
