Description
Data Transfer Enable 0
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
DTE0 bit is cleared to 0 when DTIE0 = 1, 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.
0: Data transfer is disabled
1: Data transfer is enabled

[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.
If the DTME1 bit is cleared to 0 when DTIE1B =
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.
0: Data transfer is disabled
1: Data transfer is enabled
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
