Note 1: The total output current is the sum of all the currents flowing through all the applicable ports. The total average current is an aver-
age value measured over 100 ms. The total peak current is the peak value of all the currents.
2: The peak output current is the peak current flowing in each port.
3: The average output current is an average value measured over 100 ms.
4: When the oscillation frequency has a duty cycle of 50%.
5: When using the microcomputer in low-speed mode, make sure that the sub-clock input oscillation frequency on condition that
f(XCIN) < f(XIN)/3.
