Input frequency for timers X and Y
(duty cycle 50%)
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(X

) < f(X
IN
)/3.
