Note 1.
The peak output current is the peak current flowing through any pin of the listed ports.
Note 2.
The average output current is an average current value measured over 100 ms.
Note 3.
The total peak output current is the peak current flowing throught all pins of the listed ports.
Note 4.
The total average output current is an average current value measured over 100 ms.
Note 5.
The oscillation frequency has a 50% cycle.
Note 6.
The maximum oscillation frequency of 50 KHz is for a crystal oscillator connected between XCin and XCout.
An external signal having a maximum frequency of 5 MHz can be input to XCin.
Note 7.
When using Frequency Synthesizer Circuit, minimum limit is 4 MHz. And when using USB, put internal clock
f(
.)to more than 6 MHz.
