Description
Data Transfer Enable 3
Data Transfer Enable 2
Data Transfer Enable 1
Data Transfer Enable 0
This bit is used to enable or disable the DMA data
transfer by the activation source selected by the
DTF3 to DTF0 bits in DMACRS.
When DTE = 0, data transfer is disabled and the
activation source is ignored. If the activation source
is an internal interrupt, an interrupt request is
issued to the CPU or DTC.
If the DTE bit is cleared to 0 when DTIE = 1, the
DMAC regards this as indicating the end of a
transfer, and issues a transfer end interrupt request
to the CPU or DTC.
When DTE = 1, data transfer is enabled and the
DMAC waits for a request by the activation source.
When a request is issued by the activation source,
transfer is executed.
[Clearing conditions]

•
[Setting condition]
•
When initialization is performed
When the specified number of transfers have
been completed in a transfer mode other than
repeat mode
When 0 is written to the DTE bit to forcibly
suspend the transfer, or for a similar reason
When 1 is written to the DTE bit after reading
DTE = 0
