Hi all,

On the CAP0.3 input I have pulses from an encoder and I want detect
both edges and generate interrupts. The signal is filtered so the rise
and fall time are slow (don't know exactly how long, but surely within
1ms). Is it possible that no interrupt is generated on CAP0.3, because
the signal is to slow?

I didn't found any datasheets from Philips which this is described.

Thanks for help
