But before going 14 To offload data transfers from the CPU, STM32 microprocessors (MPUs) embed 15 direct memory access controllers (DMA). 17 STM32MP1 SoCs embed both STM32 DMA and STM32 MDMA controllers. STM32 DMA 18 request routing capabilities are enhanced by a DMA request multiplexer 19 (STM32 DMAMUX). 21 **STM32 DMAMUX** [all …]
