Figure 11. Asynchronous Non-Multiplexed Address 32-bit Read Timing
Figure 11 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. The CPU_WORD_EN[1:0] inputs are used to specify which 16-bit data
memory words are valid for this transfer. If either or both these bits is ‘0’, then
the corresponding 16-bit word(s) will return a value of ‘0000’. These inputs
should be tied high if unused.
3. For register accesses, the value of CPU_WORD_EN[1:0] must be ‘11’.
