Main clock input oscillation

frequency (Note 4)

Sub-clock input oscillation frequency (Note 4, 5)

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 av-

erage 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.
