AC Characteristics
Note:
Devices should be programmed with wait states as discussed in the “Programmable Wait State” section on page 16.
Figure 22. Initial Access at 3Eh with Address Boundary Latency
Note:
If t
AVDSM
> 1 CLK cycle, wait state usage is reduced. Figure shows 40 MHz clock, handshaking enabled. Wait state usage is
4 clock cycles instead of 5. Note that t
AVDSM
must be less than 76 μs for burst operation to begin
.
