1. Minimum for AVCC is 2.7V.
2. Maximum for AVCC is 5.5V.
External Data Memory Timing
1. This assumes 50% clock duty cycle. The half period is actually the high time of the external clock, XTAL1.
2. This assumes 50% clock duty cycle. The half period is actually the low time of the external clock, XTAL1.
