Notes 1: The peak output current is the peak current flowing in each port.
2: The average output current I
OL(avg), IOH(avg) are average value measured over 100 ms.
3: When the oscillation frequency has a duty cycle of 50%.
4: When using the microcomputer in low-speed mode, set the sub-clock input oscillation frequency on condition that f(X
CIN) < f(XIN)/3.
5: When using the timer X/Y, timer 1/2, serial I/O1, serial I/O2, A-D converter, comparator, and PWM, set the main clock input oscillation frequency to
the max. 4.5V
CC–8 (MHz).
