Minimal Pulse width for triggering an EXT-Interupt

Hello to all,

I am using an STM32F2xx with 120Mhz.
An external interupt is triggered with a rising edge of a GPIO-Pin.
I looked in the datasheet, but I could not find information about the minimum pulse width at the GPIO-Pin in such  case.
How does the edge detector in the STM32F2xx work?
Does it detect the edge only if the signal is stable for a certain amount of clock cycles after the edge?

Thanks for your help!
