Notes 1. Value of current at which the device operation is guaranteed even if the current flows from VDD to an output pin.
2. Value of current at which the device operation is guaranteed even if the current flows from an output pin to GND.
3. Specification under conditions where the duty factor is 70% (time for which current is output is 0.7  t and time
for which current is not output is 0.3  t, where t is a specific time). The total output current of the pins at a duty
factor of other than 70% can be calculated by the following expression.
 Where the duty factor of I
OH is n%: Total output current of pins = (IOH  0.7)/(n  0.01)
<Example> Where the duty factor is 50%, IOH = 12 mA
Total output current of pins = (12  0.7)/(50  0.01) = 16.8 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.
Remark Unless specified otherwise, the characteristics of alternate-function pins are the same as those of port pins.
