Gentlemen
    i am couting a 60hz at ra3 in a 16c54. I am simulating this for =
right now. My problem is that i count this pulse and then it is suppose =
to increment a counter. Which it is doing fine but when i get to 60 this =
timer is supposed to reset to zero and increnment another counter.this =
next counter is supposed to count up to 60 also. then it is supposed to =
increment a third counter which is supposed to count up to 12 then reset =
to one but instead of doing that it just increments the all three =
counters and keeps going up to 255.then it resets.=20
here is the  a partial listing of my code=20
 incf   t1,f
 movlw 60   =20
 subwf t1,f
 btfsc status,2   =20
 goto t_hi
I never see it go back to the top of the program until the three =
counters all increment by one. I had a heck of time try to get simulate =
a 60hz pulse inputed to ra3  in the sim which i am not sure if i have =
that set up right. i contacted microchip and they told me to inputed it =
using clock stimulus under sim stimulus. It is set up as 3 hi and 3 lo =
pulses.
does anybody have any suggestions=20
one thing is that the pre scaler cant be used. The pc board is wired up =
for ra3.
thanks
