Notes 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 I
OL
(avg), I
OH
(avg) are 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, set the sub-clock input oscillation frequency on condition that
f(X
