I found out the same issue solved on this forum.

Here is the thread.

I set the ADCON1 = %0011111 to set digital signal and it works perfectly fine now.

I am using a 4MHZ crystal and when i program i select XT. Do we have to change something in the software to fix it ?

If i use the value PAUSE 20 it is close to 20 Seconds
