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
Note:
*
Writing 0 is possible to clear the flag.
