#config length ?

[Darrel Taylor]

If the chip only has one config word, you don't specify the word's name because it doesn't have one.
For chips with more than one config word, you must specify the word with _CONFIG1 or _CONFIG2 etc.

If you like commenting everthing really well, you can do the configs like this ...

#if __PROCESSOR__ = "16F1828"
    #config
CFG =       _FOSC_INTOSC         ; Oscillator
CFG=CFG&    _WDTE_ON             ; Watch Dog Timer 
CFG=CFG&    _PWRTE_OFF           ; Power-on Timer
CFG=CFG&    _MCLRE_OFF           ; Master Clear Reset
CFG=CFG&    _CP_ON               ; Code Protect
CFG=CFG&    _CPD_OFF             ; EEPROM Data Protect
CFG=CFG&    _BOREN_OFF           ; Brown-out Detect
CFG=CFG&    _CLKOUTEN_OFF        ; FOSC/4 Output
CFG=CFG&    _IESO_OFF            ; Internal External Switchover
CFG=CFG&    _FCMEN_OFF           ; Fail-Safe Clock Monitor
   __CONFIG _CONFIG1, CFG
 
CFG =       _WRT_OFF             ; Flash table writes
CFG=CFG&    _PLLEN_OFF           ; 4xPLL OSC multiplier
CFG=CFG&    _STVREN_OFF          ; Stack Over/Underflow
CFG=CFG&    _BORV_25             ; Brown-out voltage
CFG=CFG&    _LVP_OFF             ; Low Voltage Programming
   __CONFIG _CONFIG2, CFG
    #endconfig
#else
    #IF __PROCESSOR__ = "16F690"
    #config
CFG =       _INTRC_OSC_NOCLKOUT  ; Oscillator
CFG=CFG&    _WDT_ON              ; Watch Dog Timer
CFG=CFG&    _PWRTE_OFF           ; Power-on Timer
CFG=CFG&    _MCLRE_OFF           ; Master Clear Reset
CFG=CFG&    _CP_ON               ; Code Protect

    #endconfig
    #else
        #error "Program does not support " + __PROCESSOR__
    #endif
#endif

Still doable the long way, still easy though

       ASM                  
                          
       __CONFIG _CONFIG1, B'11111101010100'                     
                          ; 1------------- CP:    Code Protection off
                          ; -1------------ CPMX:  CCP1 on RB0 
                          ; --1----------- DEBUG: Disabled.  RB<7:6> are general purpose i/o
                          ; ---11--------- WRT:   Write Protection off
                          ; -----1-------- CPD:   Code Protection off
                          ; ------0------- LVP:   Disabled.  RB3 Is General I/O
                          ; -------1------ BOREN: Enable Brown Out Reset
                          ; --------0----- MCLRE: Disable MCLR, RA5 Is digital I/O
                          ; ----------0--- PWRTE: Enable Power-Up Timer
                          ; -----------1-- WDTEN: Enable Watch Dog Timer
                          ; ---------1--00 FOSC:  INTRC, NOCLKOUT 

       __CONFIG _CONFIG2, b'11111111111100'
                          ; xxxxxxxxxxxx-- unimplemented
                          ; ------------0- IESO: Disable Internal/External Swichover
                          ; -------------0 FCMEN: Disable Fail-Safe Clock Monitor
                          
       ENDASM

Not too hot with that method, but neat
