#config
__config _mclre_off
#endconfig
can be a bad move , all "unmentioned" config fuse settings will revert to default settings when the chip is erased


that means your config becomes possibly not whats really intended

#CONFIG
__config _EXTRC & _WDT_ON & _PWRTE_OFF & _MCLRE_OFF & _CP_OFF & _CPD_OFF & _BOD_ON & _IESO_ON & _FCMEN_ON
#ENDCONFIG


imho its best to set the lot the way you intend
