Data Transfer Enable 0
Description
Enables or disables DMA transfer for the
activation source selected by the DTF3 to DTF0
bits in DMACR of channel 0.
When DTE0 = 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
DTIE0 bit is set to 1 when DTE0 = 0, the DMAC
regards this as indicating the end of a transfer,
and issues a transfer end interrupt request to the
CPU.
When DTE0 = 1 and DTME0 = 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 DTE0 bit after reading
DTE0 = 0
Data Transfer Interrupt Enable 1B
Enables or disables an interrupt to the CPU or
DTC when transfer on channel 1 is interrupted.
When DTME1 is cleared to 0 while this bit is set
to 1, the DMAC regards this as indicating a
break in the transfer, and issues a transfer break
interrupt request to the CPU or DTC.
A transfer break interrupt can be canceled either
by clearing the DTIE1B bit to 0 in the interrupt
handling routine, or by performing processing to
continue transfer by setting the DTME1 bit to 1.
When initialization is performed
When the specified number of transfers have
been completed
When 0 is written to the DTE0 bit to forcibly
suspend the transfer, or for a similar reason
