#S32K ADC DMA ：由FTM1每隔1ms触发PDB0，PDB0设置pretrigger 3个ADC0通道，3个ADC0通道采集完一遍通过DMA中断读取。之前用过采集4路ADC并通过DMA读取，但是改成3通道时进入不了中断，不知道是不是DMA传输ADC只支持特定的通道数。
配置程序如下，接收RecordBuf_ADC0[3]是uint32_t类型，ADC通道从2~4， 请大佬们帮忙分析一下问题：
DMA->TCD[0].CSR &= ~DMA_TCD_CSR_DONE_MASK;
DMA->TCD[0].ATTR = DMA_TCD_ATTR_SMOD(4) | /*这个设置成0也不行*/
DMA_TCD_ATTR_SSIZE(2) | /*Source data transfer size32bit*/
DMA_TCD_ATTR_DMOD(0) |
DMA_TCD_ATTR_DSIZE(2); /*Destination data transfer size 32 bit*/
DMA->TCD[0].NBYTES.MLNO = DMA_TCD_NBYTES_MLNO_NBYTES(3);
DMA->TCD[0].CITER.ELINKNO = DMA_TCD_CITER_ELINKNO_CITER(3) |
DMA_TCD_CITER_ELINKNO_ELINK(0);
DMA->TCD[0].BITER.ELINKNO = DMA_TCD_BITER_ELINKNO_BITER(3) |
DMA_TCD_BITER_ELINKNO_ELINK(0);
DMA->TCD[0].SADDR = DMA_TCD_SADDR_SADDR(&(ADC0->R[2]));
DMA->TCD[0].SOFF = DMA_TCD_SOFF_SOFF(4);
DMA->TCD[0].SLAST = DMA_TCD_SLAST_SLAST(0); /*Last source address adjustment 改成-12=4byte/channel*3channel 也不行*/
DMA->TCD[0].DADDR = DMA_TCD_DADDR_DADDR(RecordBuf_ADC0);
DMA->TCD[0].DOFF = DMA_TCD_DOFF_DOFF(4);
DMA->TCD[0].DLASTSGA = DMA_TCD_DLASTSGA_DLASTSGA(-12);
DMA->TCD[0].CSR = DMA_TCD_CSR_BWC(0) |
DMA_TCD_CSR_MAJORELINK(0) |
DMA_TCD_CSR_MAJORLINKCH(0) |
DMA_TCD_CSR_ESG(0) |
DMA_TCD_CSR_DREQ(0) |
DMA_TCD_CSR_INTHALF(0) |
DMA_TCD_CSR_INTMAJOR(1) |
DMA_TCD_CSR_START(0);
