1. Typical values at 25
2. “Max” means the highest value where the pin is guaranteed to be read as low.
3. These parameters are not tested in production.
4. “Min” means the lowest value where the pin is guaranteed to be read as high.
5. Although each I/O port can sink 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. High Sink I/O pins are PD0, PD1, PD2 and PD3.
8. Although each I/O port can source more than the test conditions (10 mA at V
9. These are test limits, which account for leakage currents of the test environment. Actual device leakage currents are lower.
10. Values are with external clock using methods described in
