Figure 26. Synchronous, Non-Multiplexed Address 16-bit - Single-Word Memory Read
Timing
Figure 26 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 will not be
asserted for memory accesses, and will remain high.
