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

<Example> Where n = 80 % and IOH = - 10.0 mA

Total output current of pins = (- 10.0 × 0.7)/(80 × 0.01)

≅ - 8.7 mA

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

<Example> Where n = 80 % and IOL = 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.

Value of current at which the device operation is guaranteed even if the current flows from an output pin to

the VSS pin.

The value under the condition which satisfies the high-level output current (IOH1).

The value under the condition which satisfies the low-level output current (IOL1).

Cautions 1.

P00 and P01 do not output high level in N-ch open-drain mode.

The maximum value of VIH of P00 and P01 is VDD even in N-ch open-drain mode.

Remark

Unless specified otherwise, the characteristics of alternate-function pins are the same as those of the port.
