19.12.22 DMA Configuration Register
Name:
Access Type:
Offset:
Reset Value:
• DMA_EN: DMA Controller Enable
This register is used to enable the DMACA, which must be done before any channel activity can begin.
If the global channel enable bit is cleared while any channel is still active, then DmaCfgReg.DMA_EN still returns ‘1’ to indi-
cate that there are channels still active until hardware has terminated all activity on all channels, at which point the
DmaCfgReg.DMA_EN bit returns ‘0’.
