Bit 7—Data Transfer Master Enable 1 (DTME1): Enables or disables data transfer on channel 1.
Bit 5—Data Transfer Master Enable 0 (DTME0): Enables or disables data transfer on channel 0.
Bits 6 and 4—Data Transfer Enable (DTE): When DTE = 0, data transfer is disabled and the activation source selected
by the data transfer factor setting is ignored. If the activation source is an internal interrupt, an interrupt request is issued to
the CPU or DTC. If the DTIE bit is set to 1 when DTE = 0, the DMAC regards this as indicating the end of a transfer, and
issues a transfer end interrupt request to the CPU.
The conditions for the DTE bit being cleared to 0 are as follows:
When DTE = 1 and DTME = 1, data transfer is enabled and the DMAC waits for a request by the activation source
selected by the data transfer factor setting. When a request is issued by the activation source, DMA transfer is executed.
The condition for the DTE bit being set to 1 is as follows:
Bit 6—Data Transfer Enable 1 (DTE1): Enables or disables data transfer on channel 1.
Bit 4—Data Transfer Enable 0 (DTE0): Enables or disables data transfer on channel 0.

When initialization is performed
When the specified number of transfers have been completed
When 0 is written to the DTE bit to forcibly abort the transfer, or for a similar reason
When 1 is written to the DTE bit after the DTE bit is read as 0
