Description
Data Transfer Enable 1B
Data Transfer Enable 1A
Data Transfer Enable 0B
Data Transfer Enable 0A
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 = 0, data transfer is disabled and the
DMAC ignores the activation source selected by
the DTF3 to DTF0 bits in DMACR.
When DTE = 1, data transfer is enabled and the
DMAC waits for a request by the activation source
selected by the DTF3 to DTF0 bits in DMACR.
When a request is issued by the activation source,
DMA transfer is executed.
[Clearing conditions]

[Setting condition]
When 1 is written to the DTE bit after reading DTE
= 0
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
