Notes 1: The peak output current is the peak current flowing in each port.
2: The average output current IOL(avg), IOH(avg) are average value measured over 100 ms.
3: When the oscillation frequency has a duty cycle of 50%.
4: When using the microcomputer in low-speed mode, set the sub-clock input oscillation frequency on condition that f(XCIN) < f(XIN)/3.
