Clock input frequency for timers 2 and 4

(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 average 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 in an average value measured over 100 ms.

4: When the oscillation frequency has a 50% duty cycle.

5: When using the microcomputer in low-speed operation mode, set the sub-clock input oscillation frequency on

condition that f(XCIN) < f(XIN)/3.
