结构体成员变量说明

[struct] [1/2]

struct { ... } bus_dma_ctrl::b

Register bits.

[struct] [2/2]

struct { ... } bus_dma_ctrl::b

Register bits.

d32

uint32_t bus_dma_ctrl::d32

Raw register data.

dma_rw

uint32_t bus_dma_ctrl::dma_rw

DMA read/write indicator. 0: write; 1: read.

dma_sel_cs

uint32_t bus_dma_ctrl::dma_sel_cs

CS specified by the DMA operation.

dma_start

uint32_t bus_dma_ctrl::dma_start

DMA transfer enable control. Automatic return to 0 after the DMA transfer is complete.
