I am looking for a method to build uart rx/tx circular buffers for STM32L476 which communicate using DMA. In 40.5.2 of

http://www.st.com/content/ccc/resource/technical/document/reference_manual/02/35/09/0c/4f/f7/40/03/DM00083560.pdf/files/DM00083560.pdf/jcr:content/translations/en.DM00083560.pdf

I found a line which refers to multibuffer communication: 'Configure the DMA register as explained in multibuffer communication.' Where can I find its precise definition and sample programs?#uart #dma #stm32l4
