Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
I'm not very clear with your purpose, whether you want the GPIO to detect the number of the input pulse.
If yes, I'd like to suggest you refer to the pint_pin_interrupt demo in the LPCXpresso824MAX's code bundle whose download link is below.

Have a great day,
