Bit 3—Data Transfer Interrupt Enable 1B (DTIE1B): Enables or disables the channel 1
transfer break interrupt.
Bit 3
DTIE1B
0
1
Description
Transfer break interrupt disabled
Transfer break interrupt enabled
(Initial value)
Bit 1—Data Transfer Interrupt Enable 0B (DTIE0B): Enables or disables the channel 0
transfer break interrupt.
Bit 1
DTIE0B
0
1
Description
Transfer break interrupt disabled
Transfer break interrupt enabled
(Initial value)
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 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.
Bit 2—Data Transfer End Interrupt Enable 1A (DTIE1A): Enables or disables the channel 1
transfer end interrupt.
