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 mea-
sured 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 IOL(avg), IOH(avg) in an average value measured over 100 ms.
4: Choose an external oscillator which ensures no warps in the oscillation waveform as well as sufficient amplitude for the main clock oscillation cir-
cuit. Use according to the manufacturer’s recommended conditions.
