And I have also tried implementing it in Mikrobasic pro for pic as the compiler am used to, but my port pins(RD0 thru RD3) is displaying 8khz instead of 50hz on the COUNTER TIMER am using for simulation on proteus while the ccp1 pin is displaying 16khz which is normal. Even when I try playing around with SET_FREQ value it still doesn't save the situation. Pls I need ur help on this earnestly. May GOD reward u mightily.
