Note 1. Except for Ports P200, P214, and P215, which are input ports.

Note 2. Specification under conditions where the duty factor ≤ 70%.

The output current value that has changed to the duty factor > 70% the duty ratio can be calculated with the following expression

(when changing the duty factor from 70% to n%).

Total output current of pins = (IOH × 0.7)/(n × 0.01)

<Example> Where n = 80% and IOH = −30.0 mA

Total output current of pins = (−30.0 × 0.7)/(80 × 0.01)

≅ −26.2 mA

However, the current that is allowed to flow into one pin does not vary depending on the duty factor.

Caution: To protect the reliability of the MCU, the output current values should not exceed the values in Table 2.5.
