NOTES:
1. Tested at maximum operating frequency and guaranteed by design characterization at lower operating frequencies.
2. These are not tested. They are guaranteed by characterization.
3. Float condition occurs when maximum output current becomes less than I
in magnitude. Float delay is not fully tested.
4. These inputs may be asynchronous to CLK2. The setup and hold specifications are given for testing purposes to ensure recognition within
a specific CLK2 period.
5. Minimum time not fully tested.
