in the pic16f877 data sheet, it says that you might need to use a resistor Rs if you want to operate it in HP mode. so if you want to use a 12 MHz crystal then Rs is a necessity. up till now i have been only using the 4 MHz crystal and didnt need an accompanying resistor.
However the data sheet doesnt specify the value of resistor to be used. Could anyone help?
