Data Transfer End Interrupt Enable 1B

Data Transfer End Interrupt Enable 1A

Data Transfer End Interrupt Enable 0B

Data Transfer End Interrupt Enable 0A

These bits enable or disable an interrupt to the

CPU or DTC when transfer ends. 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.

A transfer end interrupt can be canceled either

by clearing the DTIE 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.

0: Transfer end interrupt is disabled

1: Transfer end interrupt is enabled
