i am using 16f72 pic.....on a bread board......it works perfectly at 4.433619Mhz but when i insert a 20Mhz crystal it doesnt work.....i am using mplab 7.41 and jdm programmer... i have also grounded the crystal metal case....
ya i changed the config bit to hs its working now....
but i have another problem now...i need very accurate 4.194304 Mhz source...i am using crystal for that.....now i dont know the exact value of the parallel capacitors for satbilization
