Input Ranges for PWM and Accuracy

Is the MC4X PWM Input able to monitor frequency ranges outside of it's normal function like 1000 Hz and if so what would the effects be with the resolution of the readings from the MC4X?

The frequency range for these PWM inputs is 100-500 Hz:
In some applications, a PWM sensor with 1 kHz signal could work reliably with the MC4x/XC4x. The software will handle a higher frequency, but hardware filtering can start to have an effect on accuracy.
I have successfully tested one sensor with 1 kHz PWM signal, with these characteristics that help:
-MR range 5 to 95%
-sensor of push-pull type
