Value R/W Descriptions
2 IE 0 R/W Interrupt Enable
This bit specifies whether or not an interrupt request is
generated to the CPU at the end of the DMA transfer.
Setting this bit to 1 generates an interrupt request
(DEI) to the CPU when TE bit is set to 1.
0: Interrupt request is not generated
1: Interrupt request is generated
1 TE 0 R/W* Transfer End Flag
This bit shows that DMA transfer ends. TE is set to 1
when data transfer ends when DMATCR becomes
to 0.
The TE bit is not set to 1 in the following cases.
DMA transfer ends due to a NMI interrupt or DMA
address error before DMATCR becomes to 0.
DMA transfer is ended by clearing the DE bit and
DME bit in DMA operation register (DMAOR).
Even if the DE bit is set to 1 while this bit is set to 1,
transfer is not enabled.
0: During the DMA transfer or DMA transfer has been
interrupted
1: Data transfer ends by the specified count (DMACTR
= 0)
[Clearing condition]
Writing 0 after TE = 1 read
