Description
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.
