I have a question about re-enabling a DMA memory to memory copy on LPC4370.
I have successfully set up the DMA controller to do a one time memory to memory copy using the scatter/gather method (user manual 21.8.5). If I would like to do the copy from the same source address to the destination address again, do I need to program all the same registers again?
If re-programming the registers is not needed, how is the re-enabling DMA transfer achieved?
Please help! Thank you.
