AC ELECTRICAL CHARACTERISTICS
NOTE:
1. Timing is over recommended temperature and power supply voltages.
2. Typical figures are at 25°C and are for design aid only; not guaranteed and not subject to production testing.
3. High Impedance is measured by pulling to the appropriate rail with R
4. Processor accesses are dependent on the C4i clock, and so some things are expressed as multiples of the C4i.
