Figure 15-3, Figure 15-4, and Figure 15-5 illustrate the memory and I/O read and write cycles.
The Rabbit operates at 2 clocks per bus cycle plus any wait states that might be specified.
The following memory read time delays were measured.
The measurements were taken at the 50% points under the following conditions.
• T = -40°C to 85°C, V = 5.0 V ±10%
• Internal clock to nonloaded CLK pin delay ≤ 1 ns @ 85°C/4.5 V
The following memory write time delays were measured.
The measurements were taken at the 50% points under the same conditions that the mem-
ory read delays were measured.
