Bit 8—Data Transfer Acknowledge 0A (DTA0A): Enables or disables clearing, when DMA transfer is performed, of
the internal interrupt source selected by the channel 0A data transfer factor setting.
Bits 7 to 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 or DTC.
The conditions for the DTE bit being cleared to 0 are as follows:
When DTE = 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 7—Data Transfer Enable 1B (DTE1B): Enables or disables data transfer on channel 1B.
Bit 6—Data Transfer Enable 1A (DTE1A): Enables or disables data transfer on channel 1A.
Bit 5—Data Transfer Enable 0B (DTE0B): Enables or disables data transfer on channel 0B.
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 abort the transfer, or for a similar reason
When 1 is written to the DTE bit after the DTE bit is read as 0
