It would be a bit different if it's not a 685. Try something like this, and make sure your
device programmer keeps your config settings. You'll also need to comment out the default
config setting in the 16F684.INC file for MPASM.

Code:
@ __CONFIG _INTOSCIO & _WDT_ON & _MCLRE_OFF & _CP_OFF

ANSEL = $00
OSCCON = %01100000
CMCON0 = 7
TRISA = $00
TRISC = $00
