Configure the channel attributes as follows, or use the following driver library function:
uDMAChannelAttributeDisable(uint32_t ui32Base, uint32_t ui32ChannelNum, uint32_t ui32Attr)
- Program bit 0 of the DMA Set Channel Priority register, UDMA:SETCHNLPRIORITY, or the DMA Clear Channel Priority register, UDMA:CLEARCHNLPRIORITY, to set the channel to high priority or default priority.
- Set bit 0 of the DMA Clear Channel Primary Alternate register, UDMA:CLEARCHNLPRIALT, to select the primary channel control structure for this transfer.
- Set bit 0 of the DMA Channel Clear Useburst register, UDMA:CLEARBURST, to allow the μDMA controller to respond to single requests and burst requests.
- Set bit 0 of the DMA Clear Channel Request Mask register, UDMA:CLEARREQMASK, to allow the μDMA controller to recognize requests for this channel.
