I compile the code and I got an error message:When I delete this line:@ DEVICE pic16F628A, XT_OSC, WDT_OFF, PWRT_OFF, BOD_OFF, MCLR_ON, LVP_OFF, CPD_OFF, PROTECT_OFF
there is no Error.When the line isn't deleted there is an error,that is saying Illegal opcode(pic16F628A) This error is when I use pic16F648A
