2. “Min” means the lowest value where the pin is guaranteed to be read as high.
3. “Max” means the highest value where the pin is guaranteed to be read as low.
4. Although each I/O port can sink more than the test conditions (10 mA at V
5. Although each I/O port can source more than the test conditions (10 mA at V
6. The RESET pin must tolerate high voltages when entering and operating in programming modes and, as a consequence,
7. Values are with external clock. Power Reduction is enabled (PRR = 0xFF) and there is no I/O drive.
8. BOD Disabled.
