You do this with the __CONFIG directive:

_MCLRE_ON                    EQU     H'0FFF'
_MCLRE_OFF                   EQU     H'0FEF'
_CP_ON                       EQU     H'0FF7'
_CP_OFF                      EQU     H'0FFF'
_WDT_ON                      EQU     H'0FFF'
_WDT_OFF                     EQU     H'0FFB'
_LP_OSC                      EQU     H'0FFC'
_XT_OSC                      EQU     H'0FFD'
_IntRC_OSC                   EQU     H'0FFE'
_ExtRC_OSC                   EQU     H'0FFF'

__CONFIG _MCLRE_OFF & _CP_OFF & _WDT_OFF & _IntRC_OSC
