Figure 35. Synchronous, Multiplexed Address 16-bit Single-Word Memory Write Timing
Figure 35 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, and
de-asserted high at the end of the transfer.
2. For 16-bit accesses, CPU_WORD_EN[1:0] must be ‘11’ through the full
transfer cycle.
3. Unless the Total-AceXtreme command FIFO is full, CPU_nSTOP is not
asserted for write accesses, and will remain high.
