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
