Hello,

What is the shortest pulse you can mesure on LPC capture module?

I am trying to measure some pulses using the capture hardware on LPC 
chips. The processor is running at 48Mhz and my capture module is 
running at 1us/ticks

Connecting a function generator, I can read valid results up to 1Khz. 
When I go over 10KHz, the reading is not stable at all! About 10% up 
and down.

Thanks,

Gus
