Hello Everyone. I just ran across a very strange problem and wanted to know if anyone knows why. This header file for a 12F675 works perfectly. However if you put "HIGH GPIO.2" underneath "GPIO = %00000000" it causes GPIO.4 to go high. I didn't check if others were going high as I have a LED on GPIO.4. Why did this happen? Thank you.
