Notes 1. Value of current at which the device operation is guaranteed even if the current flows from pins EVDD0, EVDD1

and VDD to an output pin.

2. These output current values are obtained under the condition that the duty factor is no greater than 70%.

The output current values when the duty factor is changed to a value greater than 70% can be calculated from

the following expression (when the duty factor is changed to n%).

• 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

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 P10 to P17, P32, P60 to P63, P70 to P72, and P120 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.
