External Request/Cluster Transfer Mode/Cycle Steal Mode
With external requests, a cluster-size transfer is performed continuously. The start timing of the
next cluster transfer is the same as for normal transfer mode.
If a transfer request is generated for another channel, an EXDMA cycle for the other channel is
generated before the next cluster transfer.
The cluster transfer mode (read address mode and write address mode) can not be used with the
cluster transfer mode (dual address mode) among more than one channel at the same time. When
using the cluster transfer mode (read address mode and write address mode), do not set the cluster
transfer mode for another channel.
The EDREQ pin sensing timing is different for low level sensing and falling edge sensing. The
same applies to transfer request acceptance and transfer start timing.
Figures 11.67 to 11.69 show operation timing examples for various conditions.
