Transfer End Flag
Shows that DMA transfer ends. The TE bit is set to 1
when data transfer ends when TCR becomes to 0.
The TE bit is not set to 1 in the following cases.
•
DMA transfer ends due to an NMI interrupt or DMA
address error before TCR is cleared to 0.
•
DMA transfer is ended by clearing the DE bit and
DME bit in DMAOR.
To clear the TE bit, the TE bit should be written to 0
after reading 1.
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
[Clearing condition]
Writing 0 after TE = 1 read
1: DMA transfer ends by the specified count (TCR = 0)
0 DE 0 R/W
DMA
Enable
Enables or disables the DMA transfer. In auto request
mode, DMA transfer starts by setting the DE bit and
DME bit in DMAOR to 1. In this time, all of the bits TE,
NMIF, and AE in DMAOR must be 0. In an external
request or peripheral module request, DMA transfer
starts if DMA transfer request is generated by the
devices or peripheral modules after setting the bits DE
and DME to 1. In this case, however, all of the bits TE,
NMIF, and AE must be 0, which is the same as in the
case of auto request mode. Clearing the DE bit to 0 can
terminate the DMA transfer.
0: DMA transfer disabled
1: DMA transfer enabled
To abort the DMA transfer in on-chip peripheral module
request mode, clear the DE bit to 0 while the DMA
request from the corresponding peripheral module is
cleared.
Note:
*
Writing 0 is possible to clear the flag.
