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 is an average value measured over 100 ms.
4: When the A/D converter is used, refer to the recommended operating condition for A/D converter.
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.
