Notes 1 : It is except to use P50 as XCIN.
2 : The average output current IOH (avg) and IOL (avg) are the average value during a 100 ms.
3 : Oscillation frequency is at 50% duty cycle.
4 : When used in the low-speed mode, the clock oscillation frequency for clock function should be f(XCIN) < f(XIN) / 3.
