Bit 4—Data Transfer Enable 0 (DTE0): Enables or disables data transfer on channel 0.

Bits 3 and 1—Data Transfer Interrupt Enable B (DTIEB): These bits enable or disable an
interrupt to the CPU or DTC when transfer is interrupted. If the DTIEB bit is set to 1 when
DTME = 0, 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 DTIEB bit to 0 in the interrupt
handling routine, or by performing processing to continue transfer by setting the DTME bit to 1.
Bit 3—Data Transfer Interrupt Enable 1B (DTIE1B): Enables or disables the channel 1
transfer break interrupt.

Bit 1—Data Transfer Interrupt Enable 0B (DTIE0B): Enables or disables the channel 0

Bits 2 and 0—Data Transfer End Interrupt Enable A (DTIEA): These bits enable or disable
an interrupt to the CPU or DTC when transfer ends. If the DTIEA 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.
A transfer end interrupt can be canceled either by clearing the DTIEA bit to 0 in the interrupt
handling routine, or by performing processing to continue transfer by setting the transfer counter
and address register again, and then setting the DTE bit to 1.
