Fixed (code implementation)!
Because interrupt occur very frequently, command like Serial.print don't feet wheel when is used inside ISR function, because require much time.
So i keep only minimal code in ISR and move Serial.println in loop routine. Now i can see how counter is incremented and everything work as expected.
In conclusion, pin change interrupts can be used with Hall sensor from motors if don't have disposable an external interrupt.
In my case a see about 600 changes/per second when using external intrerupt (so 300 rising or falling interrupts) and when i use pin change interrupts i got same value, so at this speed work very well.
