External clock on 16f819 problem.

[Demon]

Wouldn't that need a CONFIG fuse?

Dave, do you have an example from one of your programs?

EDIT: These are the available fuses for a 16F819:

_CP_ALL                      EQU     H'1FFF'
_CP_OFF	                     EQU     H'3FFF'
_CCP1_RB2		     EQU     H'3FFF'
_CCP1_RB3                    EQU     H'2FFF'
_DEBUG_OFF                   EQU     H'3FFF'
_DEBUG_ON                    EQU     H'37FF'
_WRT_ENABLE_OFF              EQU     H'3FFF'
_WRT_ENABLE_512              EQU     H'3DFF'
_WRT_ENABLE_1024             EQU     H'3BFF'
_WRT_ENABLE_1536             EQU     H'39FF'
_CPD_ON                      EQU     H'3EFF'
_CPD_OFF                     EQU     H'3FFF'
_LVP_ON                      EQU     H'3FFF'
_LVP_OFF                     EQU     H'3F7F'
_BODEN_ON                    EQU     H'3FFF'
_BODEN_OFF                   EQU     H'3FBF'
_MCLR_ON		     EQU     H'3FFF'
_MCLR_OFF                    EQU     H'3FDF'
_PWRTE_OFF                   EQU     H'3FFF'
_PWRTE_ON                    EQU     H'3FF7'
_WDT_ON                      EQU     H'3FFF'
_WDT_OFF                     EQU     H'3FFB'
_EXTRC_CLKOUT		     EQU     H'3FFF'
_EXTRC_IO		     EQU     H'3FFE'
_INTRC_CLKOUT                EQU     H'3FFD'
_INTRC_IO		     EQU     H'3FFC'
_EXTCLK			     EQU     H'3FEF'
_HS_OSC                      EQU     H'3FEE'
_XT_OSC                      EQU     H'3FED'
_LP_OSC                      EQU     H'3FEC'

And these are the default settings (PM and MPASM):

        device  pic16F819, hs_osc, wdt_on, pwrt_on, lvp_off, protect_off
        ...    else
        ...        __config _HS_OSC & _WDT_ON & _PWRTE_ON & _LVP_OFF & _CP_OFF
