Is there a chance I'll read memory whilst the DMA is still in possession of data?</SPAN><BR /><BR /><SPAN>Many thanks</SPAN></BODY></HTML> Wed, 15 Jun 2016 17:00:14 GMT https://community.nxp.com/t5/LPC-Microcontrollers/DMA-and-UART/m-p/525895#M8531 lpcware 2016-06-15T17:00:14Z Re: DMA and UART https://community.nxp.com/t5/LPC-Microcontrollers/DMA-and-UART/m-p/525896#M8532 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by jdurand on Tue Oct 02 08:58:30 MST 2012</STRONG><BR /><SPAN>You can use the barrier instructions to make sure everything is done.</SPAN></BODY></HTML> Wed, 15 Jun 2016 17:00:15 GMT https://community.nxp.com/t5/LPC-Microcontrollers/DMA-and-UART/m-p/525896#M8532 lpcware 2016-06-15T17:00:15Z
