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 f(X
CIN
) is less than
f(X
IN
)/3.
