Notes 1: Average output current is the average value of a 100 ms interval.
2: The sum of IOL(peak) for ports P0, P1, P2, P3, and P8 must be 80 mA or less,
the sum of IOH(peak) for ports P0, P1, P2, P3, and P8 must be 80 mA or less,
the sum of IOL(peak) for ports P4, P5, P6, and P7 must be 80 mA or less, and
the sum of IOH(peak) for ports P4, P5, P6, and P7 must be 80 mA or less.
