DMA中断标志清除寄存器, 该寄存器同样有2个:DMA_LIFCR和DMA_HIFCR,同样是每个寄存器控制4个数据流,DMA_LIFCR寄存器用于管理数据流0~3,而DMA_ HIFCR用于管理数据流4~7。这两个寄存器各位描述都完全一模一样,只是管理的数据流不一样。 这里,我们仅以DMA_LIFCR寄存器为例进行介绍,DMA_LIFCR各位描述如下图所示:...

ifcr = DMA1->IFCR; isr = DMA1->ISR; sr = TIM1->SR; dier = TIM1->DIER; egr = TIM1->EGR; I wasn't sure where to set the breakpoint, so I generated a few rising edges on EFR then stopped in the while loop where these were assigned. All are 0 except ...

ATA requires that all DMA transfers begin and end on word boundaries. Because of this, a large amount of machinery grew up in ide to adjust scatterlists on this basis. However, as of 2.5, the block layer has a dma_alignment variable which ensures both the beginning and length of a ...
