MCASP里的AFIFO_WFIFOCTL、AFIFO_RFIFOCTL使能后，同时把FMT的BUSEEL设为DMA数据，产生AXEVT、AREVT事件，请问是到EDMA吗？

TI 的员工，你们应很有耐心哈，帮忙解释下了，虽然很简单，但也要你们帮助哈，非常感谢！！！

是EDMA，可以参考STARTERWARE里面的代码
下面别是发送和接受的EDMA参数
static struct EDMA3CCPaRAMEntry const txDefaultPar =
[
(unsigned int)(EDMA3CC_OPT_DAM | (0x02 << 8u)), /* Opt field */
(unsigned int)loopBuf, /* source address */
(unsigned short)(BYTES_PER_SAMPLE), /* aCnt */
(unsigned short)(NUM_SAMPLES_LOOP_BUF), /* bCnt */
(unsigned int) SOC_MCASP_0_DATA_REGS, /* dest address */
(short) (BYTES_PER_SAMPLE), /* source bIdx */
(short)(0), /* dest bIdx */
(unsigned short)(PAR_TX_START * SIZE_PARAMSET), /* link address */
(unsigned short)(0), /* bCnt reload value */
(short)(0), /* source cIdx */
(short)(0), /* dest cIdx */
(unsigned short)1 /* cCnt */
];
/*
** Default paRAM for Receive section.
*/
static struct EDMA3CCPaRAMEntry const rxDefaultPar =
[
(unsigned int)(EDMA3CC_OPT_SAM | (0x02 << 8u)), /* Opt field */
(unsigned int)SOC_MCASP_0_DATA_REGS, /* source address */
(unsigned short)(BYTES_PER_SAMPLE), /* aCnt */
(unsigned short)(1), /* bCnt */
(unsigned int)rxBuf0, /* dest address */
(short) (0), /* source bIdx */
(short)(BYTES_PER_SAMPLE), /* dest bIdx */
(unsigned short)(PAR_RX_START * SIZE_PARAMSET), /* link address */
(unsigned short)(0), /* bCnt reload value */
(short)(0), /* source cIdx */
(short)(0), /* dest cIdx */
(unsigned short)1 /* cCnt */
];

恩，非常感谢！ SOC_MCASP_0_DATA_REGS、SOC_MCASP_0_DATA_REGS为其AFIFO发送和接收的地址值了，已经弄明白了。

FMT的BUSEEL一定要设为DMA数据？
