Timer0 as counter

Hi everyone
Timer0 is clocked ext on RA4 and RA4 is a Schmitt Trigger all the other PORTA pins is TTL.
Timer0 can count pulses up to 50Mhz.
Where in the datasheet is the speed specified that RA4 will no longer be able to count?
Thanks in advance.

    The "Electrical Characteristics" chapter of your PIC datasheet.

    Which PIC?

    PEBKAC / EBKAC / POBCAK / PICNIC (eventually see en.wikipedia.org)
