NOTES:
1. Processor clock (CLK2) rise time and fall time are not tested.
2. A float condition occurs when the maximum output current becomes less than ILO. Float delay is not tested, but should be
no longer than the valid delay.
3. Meeting RESET setup and hold times is an optional method of synchronizing your clocks. If you decide to use an asyn-
chronous reset, synchronizing the clock can be accomplished by using AS.
