I made an earlier post asking about that. I'm using an external oscilator set up with a 20MHz oscillator and with the input and out puts going through 47uF capacitors to ground and their perspective input and output oscilator pins on the PIC. When I used PAUSE 500 for a half second pause, it paused for a lot longer than half a second. I lowered it down to 2 and it paused for about a second so I just went with it and just posted a question about it on here
