I used 66AK2H06 and want to trigger the EDMA3 with timer output.
I found the following "CSL_EDMACC_1_TIMER_8_INTL". I think it means the timer 8 output low to trigger EDMACC1 event, right?
Where is he function to call this value, or to use this parameter?
//#define CSL_EDMACC_1_TIMER_8_INTL (0x00000016) in csl_device_interrupt.h
And channelNum =1 in the following program, what is the channelNum means?
/* Channel Open Global */
chAttr.regionNum = CSL_EDMA3_REGION_GLOBAL;
chAttr.chaNum = channelNum;
hChannel = CSL_edma3ChannelOpen(&chObj, instNum, &chAttr, &status);
What is the "1" means in the function pramameters?
/* Map the DMA Channel to the appropriate PARAM Block. */
CSL_edma3HwChannelSetupParam(hChannel, 1) ;
/* Obtain a handle to parameter set */
hParamBlock1 = CSL_edma3GetParamHandle(hChannel, 1, &status);
Thanks,
