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.
