Hi,

I would need help on LPC1788 interrupt speed.

Is there any way we can increase interrupt speed of MCU? Or how to calculate interrupt speed of my MCU?

I have some missing pulse when MCU triggered with some high speed signal. If I slow down my pulse speed, I see more triggered count than using machine speed.

Currently my MCU running at 120MHz. I have changed peripheral clock from 60Mhz to 120Mhz but it doesn't help in this case.

#define PCLKSEL_Val           0x00000001 //0x00000002

Please advise. Thanks.
