1. Applicable for all except PC0.
2. “Max” means the highest value where the pin is guaranteed to be read as low.
3. “Min” means the lowest value where the pin is guaranteed to be read as high.
4. Although each I/O port can sink more than the test conditions (5 mA at VCC = 3.3V) under steady state conditions (non-tran-

sient, the following must be observed:
- The sum of all IOL should not exceed 20 mA.
If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater
than the listed test condition.
transient, the following must be observed:
- The sum of all IOH should not exceed 2 mA.
