Register 14: DMA Channel Enable Set (DMAENASET), offset 0x028
Each bit of the DMAENASET register represents the corresponding DMA channel. Writing a 1
enables the DMA channel. Reading the register returns the enable status of the channels. If a
channel is enabled but the request mask is set (DMAREQMASKSET), then the channel can be
used for software-initiated transfers.
