Notes 1. Value of current at which the device operation is guaranteed even if the current flows from the EVDD0, VDD
pins to an output pin.
2. However, do not exceed the total current value.
3. 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 = (I
OH × 0.7)/(n × 0.01)
<Example> Where n = 80% and I
OH = −10.0 mA
Total output current of pins = (−10.0 × 0.7)/(80 × 0.01) ≅ −8.7 mA
However, the current that is allowed to flow into one pin does not vary depending on the duty factor. A
current higher than the absolute maximum rating must not flow into one pin.
Caution P00, P02 to P04, P10 to P15, P43, P50, P71, and P74 do not output high level in N-ch open-drain mode.
Remark Unless specified otherwise, the characteristics of alternate-function pins are the same as those of the port
pins.
