Hello,

Maybe someone can point me.

I want to make pulse counter. Speed until 40pulses/s

What NXP mechanism exists.

For example with PIC i have used a PORTB interupt.

Thank you
PRanas

You can use GPIO interrupt using the registers IO0IntEnr for any type of edge i.e. rising falling or both.
Use the timer to get the time of 1 sec.
