MSP430FR5994 Using ADC12 With the DMA Controller 求TI员工解答

1. 想把ADC的数据通过DMA搬移到RAM，达到一定数量后再写入SD卡？应该如何操作，官网上似乎没有具体的示例代码？

2. 我想通过配置DMA，使能中断来实现，目标地址数据累计到一定量后，触发中断，但是发现配置后影响ADC也不工作了，下面是DMA配置代码，求解答

ptempData = malloc(DataSize);
__data16_write_addr((unsigned short) &DMA0SA,(unsigned long) &ADC12MEM0);// Source block address
__data16_write_addr((unsigned short) &DMA0DA,(unsigned long) ptempData); // Destination single address
DMA0SZ = DataSize; 
DMACTL0 |= DMA0TSEL_26;
DMA0CTL = DMADT_4 | DMASRCINCR_0 | DMADSTINCR_3 | DMAIE;
DMA0CTL |= DMAEN; //Enable DMA0
