When nSELECT is asserted (low), the Total-AceXtreme® is selected for thisdata transfer. nSELECT must be asserted through the full transfer cycle. InAsynchronous mode, nSELECT may be kept low for consecutive transactionsby the Total-AceXtreme.2. For 16-bit accesses, CPU_WORD_EN[1:0] must be ‘11’ through the fulltransfer cycle.3. For register accesses, the value of CPU_WORD_EN[1:0] must be ‘11’.CPU_WORD_EN[1:0]MEM_nREGMSW_nLSWnDATA_RDYCPU_DATACPU_ADDRnDATA_STRBnSELECTRD_nWRtRDDtSS tSHtWait tRDDtWaitData AtOHZtOH tOHZtOHtAStAStAStASData BtDDtAHtAHtAHAddresstAS tAHtAS tAHtDD
