 * Function:        void DmaChnSetEventControlFlags(DmaChannel chn, DmaEvCtrlFlags dmaEvCtrl)
 *
 * PreCondition:    chn	- valid DMA channel
 *
 * Input:			chn			- DMA channel number
 * 					dmaEvCtrl	- 	either a DmaEvCtrl structure field, carrying the following info:
 * 										- AIRQEN: enable/disable the abort IRQ action
 * 										- SIRQEN: enable/disable the start IRQ action
 * 										- PATEN: enable/disable the pattern match and abort
 * 									or any of the DmaEvCtrlFlags:
 * 										DMA_EV_ABORT_IRQ_EN|DMA_EV_START_IRQ_EN|DMA_EV_MATCH_EN
 *
 *
 * Output:          None
 *
 * Side Effects:    None
 *
 * Overview:		The function sets the events that start and abort the transfer
 * 					for the selected DMA channel.
 * 					Multiple flags can be orr-ed together. Any flag that is set in the eFlags will be
 * 					enabled for the selected channel, the other channel event flags won't be touched.
 *
 * Note:            None.
 *
 * Example:			either:
 * 						DmaChnSetEventControlFlags(3, DMA_EV_MATCH_EN|DMA_EV_START_IRQ_EN;
 * 					or:
 * 						DmaEvCtrl evCtrl; evCtrl.w=0; evCtrl.PATEN=1; evCtrl.SIRQEN=1;
 * 						DmaChnSetEventControlFlags(3, evCtrl.w);
