Hello,
    I'm trying to use the timer1 (TMR1) with the PIC16C73A, but I've
some problems,
I program the interrruption, and it works (T1CON=b'00001101') when I use
the internal clock, but when I program the external one
(T1CON=b'00001111') it never triggers the interruptions,does any one
know why?

                                                                Ferran
