Figure 28. Synchronous, Non-Multiplexed Address - 16-bit Single-Word Memory Write

Timing

Figure 28 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.
