 * Function:        void DmaChnClrEvFlags(DmaChannel chn, DmaEvFlags eFlags)
 *
 * PreCondition:    chn	- valid DMA channel
 *
 * Input:			chn		- DMA channel number
 * 					eFlags	- event flags with the following significance:
 * 								- DMA_EV_ERR: address error event
 * 								- DMA_EV_ABORT: transfer abort event
 * 								- DMA_EV_CELL_DONE: cell transfer complete event
 * 								- DMA_EV_BLOCK_DONE: block transfer complete event
 * 								- DMA_EV_DST_HALF: destination half event
 * 								- DMA_EV_DST_FULL: destination full event
 * 								- DMA_EV_SRC_HALF: source half event
 * 								- DMA_EV_SRC_FULL: source full event
 * 								- DMA_EV_ALL_EVNTS: all of the above flags
 *
 * Output:          None
 *
 * Side Effects:    None
 *
 * Overview:		The function clears the event flags for the selected DMA channel.
 * 					Multiple flags can be orr-ed together. Any flag that is set in the eFlags will be
 * 					cleared for the selected channel, the other channel event flags won't be touched.
 *
 * Note:            None.
