NOTES:
1. All timings referenced to 1.5V. All timings measured with respect to a 2.5ns rise and fall time.
2. The AC values listed here reference timing diagrams contained in the
R3081 Family Hardware User's Manual.
3. Guaranteed by design.
4. This parameter is used to derate the AC timings according to the loading of the system. This parameter provides a deration for loads over the specified
test condition; that is, the deration factor is applied for each 25pF over the specified test load condition.
5. In 1x clock mode, t22 is replaced by t44/2.
6. In 1x clock mode, the design guarantees that the input clock rise and fall times can be as long as 5ns, 3ns for 40MHz and 50MHz.
7. When using the Reduced Frequency feature, the minimum allowed internal CPU speed is 0.5 MHz.
