Description
Data Transfer Enable
Enables or disables data transfer on the corresponding
channel. When this bit is set to 1, this indicates that an
EXDMA operation is in progress.
When auto-request mode is specified, transfer
processing begins when this bit is set to 1. With
external requests, transfer processing begins when a
transfer request is issued after this bit has been set to
1. When this bit is cleared to 0 during an EXDMA
operation, transfer is halted.
If this bit is cleared to 0 during an EXDMA operation in
block transfer mode, this bit is cleared to 0 on
completion of the currently executing one-block
transfer. When this bit is cleared to 0 during an EXDMA
operation in cluster transfer mode, this bit is cleared to
0 on completion of the currently executing one-cluster
transfer.
If an external source that ends (aborts) transfer occurs,
this bit is automatically cleared to 0 and transfer is
terminated.
Do not change the operating mode, transfer method, or
other parameters while this bit is set to 1.
0: Data transfer disabled
1: Data transfer enabled (during an EXDMA operation)
