Description
Data Transfer Enable 1
Enables or disables DMA transfer for the activation
source selected by the DTF3 to DTF0 bits in
DMACR of channel 1.
When DTE1 = 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 DTE1 bit is
cleared to 0 when DTIE1 = 1, the DMAC regards
this as indicating the end of a transfer, and issues a
transfer end interrupt request to the CPU.
When DTE1 = 1 and DTME1 = 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, DMA transfer is executed.

[Setting condition]
When 1 is written to the DTE1 bit after reading
DTE1 = 0
When initialization is performed
When the specified number of transfers have
been completed
When 0 is written to the DTE1 bit to forcibly
suspend the transfer, or for a similar reason
