Notes 1.

When P60 or P61 is set to Nch open drain mode, it does not drive high level output.

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 = -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. A

current higher than the absolute maximum rating must not flow into one pin.

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 (IOL × 0.7)/(n × 0.01)

<Example> Where n = 80% and IOL = 40.0 mA

Total output current of pins = (40.0

× 0.7)/(80 × 0.01) = 35.0 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 Different voltage between EVDD and VDD is allowed only when LCDM register is initial value.
