Expand description

DMA Memory to Memory pseudo-Peripheral

This is a pseudo-peripheral that allows for memory to memory transfers. It is not a real peripheral, but a way to use the DMA engine for memory to memory transfers.

Fields§

§rx: Mem2MemRx<'d, Dm>

RX Half

§tx: Mem2MemTx<'d, Dm>

TX Half
