External Data Memory Characteristics
1. All DC Characteristics contained in this datasheet are based on simulation and characterization of other AVR microcontrol-
2. This assumes 50% clock duty cycle. The half period is actually the high time of the external clock, XTAL1.
3. This assumes 50% clock duty cycle. The half period is actually the low time of the external clock, XTAL1.
