Descriptions
This bit enabler or disables the DMA transfer. In an 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 in DMAOR, and AE must be 0's. 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's an 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
