24.4.22 DMAC Configuration Register
Name: DMAC_DmaCfgReg
Address: 0x00800398
Access: Read/Write
• DMA_EN: DMA Controller Enable
0: DMAC Disabled
1: DMAC Enabled.
This register is used to enable the DMAC, 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 DMAC_DmaCfgReg.DMA_EN still returns
‘1’ to indicate that there are channels still active until hardware has terminated all activity on all channels, at which point the
DMAC_DmaCfgReg.DMA_EN bit returns ‘0’.
