Figure 14. Asynchronous Non-Multiplexed Address 16-bit Write Timing
Figure 14 Notes:
1. When nSELECT is asserted (low), the Total-AceXtreme® is selected for this
data transfer. nSELECT must be asserted through the full transfer cycle. In
Asynchronous mode, nSELECT may be kept low for consecutive transactions
by the Total-AceXtreme.
2. For 16-bit accesses, CPU_WORD_EN[1:0] must be ‘11’ through the full
transfer cycle.
