Note : The total output current is the sum of all the currents flowing through all the applicable ports. The total average current is an average value measured
over 100 ms. The total peak current is the peak value of all the currents.

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.
5: When using the timer X/Y, timer 1/2, serial I/O1, serial I/O2, A-D converter, comparator, and PWM, set the main clock input oscillation frequency to
the max. 4.5VCC–8 (MHz).
