Description
Data Transfer Enable
Enables/disables a data transfer for the corresponding
channel. When this bit is set to 1, it indicates that the
DMAC is in operation.
Setting this bit to 1 starts a transfer when the auto-
request is selected. When the on-chip module interrupt
or external request is selected, a transfer request after
setting this bit to 1 starts the transfer. While data is
being transferred, clearing this bit to 0 stops the
transfer.
In block transfer mode, if writing 0 to this bit while data is
being transferred, this bit is cleared to 0 after the current
1-block size data transfer.
If an event which stops (sustains) a transfer occurs
externally, this bit is automatically cleared to 0 to stop
the transfer.
Operating modes and transfer methods must not be
changed while this bit is set to 1.
0: Disables a data transfer
1: Enables a data transfer (DMA is in operation)
