Notes:
1. “Max” means the highest value where the pin is guaranteed to be read as low
2. “Min.” means the lowest value where the pin is guaranteed to be read as high
3. Although each I/O port can source more than the test conditions (20 mA at V
conditions (non-transient), the following must be observed:
ATmega48A/48PA/88A/88PA/168A/168PA/328/328P:
1] The sum of all I
