AT32F425 DMA Application Note
●The AT32F425 series MCU features one DMA controller (DMA1). Each controller contains seven DMA channels, and DMA requests from peripherals can be mapped to any channel. This application note mainly introduces DMA functions and related application cases.
■Introduction:
●Direct memory access (DMA) controller is designed for 32-bit MCU applications with the aim of enhancing system performance and reducing the generation of interrupts.
●DMA controller provides seven channels for memory-to-memory, memory-to-peripheral and peripheral-to-memory transfers, and for flexible mapping of DMA requests from peripherals.
