 * Function:        void DmaGetStatus(DmaStatus* pStat)
 *
 * PreCondition:    pStat	- valid pointer
 *
 * Input:			pStat	- pointer to a DmaStatus structure to store the current DMA controller
 * 							status, carrying the following info:
 * 								- chn:	the last active DMA channel
 * 								- rdOp: the last DMA operation, read/write
 * 								- lastAddress: the most recent DMA address
 *
 * Output:          None
 *
 * Side Effects:    None
 *
 * Overview:		The function updates the info for the current DMA controller status.
 * 					It updates the last DMA: operation, channel used and address.
 *
 * Note:            None.
