Discovering PIC 16F18446 - TOGGLE "ASM WARNING - Invalid RAM location"

[richard]

First or upper code in your previous message dosen't work

this works perfectly for me, i doubt you implemented it exactly as posted
i notice you don't set the pins used to digital mode

another correct way

' PIC 16F18426
#CONFIG
    __config _CONFIG1, _FEXTOSC_OFF & _RSTOSC_HFINT1 & _CLKOUTEN_OFF & _CSWEN_ON & _FCMEN_ON
    __config _CONFIG2, _MCLRE_ON & _PWRTS_PWRT_64 & _LPBOREN_OFF & _BOREN_SBOREN & _BORV_LO & _ZCDDIS_OFF & _PPS1WAY_OFF & _STVREN_ON
    __config _CONFIG3, _WDTCPS_WDTCPS_31 & _WDTE_SWDTEN & _WDTCWS_WDTCWS_7 & _WDTCCS_LFINTOSC
    __config _CONFIG4, _BBSIZE_BB512 & _BBEN_OFF & _SAFEN_OFF & _WRTAPP_OFF & _WRTB_OFF & _WRTC_OFF & _WRTD_OFF & _WRTSAF_OFF & _LVP_OFF
    __config _CONFIG5, _CP_OFF
#ENDCONFIG


' ====== DEFINES ===================================================================================
    DEFINE OSC 4
    ANSELC = $DF;
    OSCCON1 = $60; // CSWHOLD may proceed; SOSCPWR Low power;
    OSCCON3 = 0;  // MFOEN disabled; LFOEN disabled; ADOEN disabled; SOSCEN disabled; EXTOEN disabled; HFOEN disabled;
    OSCEN = 0 ;    // HFFRQ 4_MHz; 
    OSCFRQ = 2;  // HFTUN 0; 
    OSCTUNE = 0


' ====== TEST PROGRAM ==============================================================================
TEST:


    TOGGLE PORTC.5
    pause 500
    
GOTO TEST
END

Richard, this is your exact code (no changes at all) and it lights the LED steady ON:

' PIC 16F18446
#CONFIG
    __config _CONFIG1, _FEXTOSC_OFF & _RSTOSC_HFINT1 & _CLKOUTEN_OFF & _CSWEN_ON & _FCMEN_ON
    __config _CONFIG2, _MCLRE_ON & _PWRTS_PWRT_64 & _LPBOREN_OFF & _BOREN_SBOREN & _BORV_LO & _ZCDDIS_OFF & _PPS1WAY_OFF & _STVREN_ON
    __config _CONFIG3, _WDTCPS_WDTCPS_31 & _WDTE_SWDTEN & _WDTCWS_WDTCWS_7 & _WDTCCS_LFINTOSC
    __config _CONFIG4, _BBSIZE_BB512 & _BBEN_OFF & _SAFEN_OFF & _WRTAPP_OFF & _WRTB_OFF & _WRTC_OFF & _WRTD_OFF & _WRTSAF_OFF & _LVP_OFF
    __config _CONFIG5, _CP_OFF
#ENDCONFIG


' ====== DEFINES ===================================================================================
    DEFINE OSC 4
    ANSELB = $B0;
    OSCCON1 = $60; // CSWHOLD may proceed; SOSCPWR Low power;
    OSCCON3 = 0;  // MFOEN disabled; LFOEN disabled; ADOEN disabled; SOSCEN disabled; EXTOEN disabled; HFOEN disabled;
    OSCEN = 0 ;    // HFFRQ 4_MHz; 
    OSCFRQ = 2;  // HFTUN 0; 
    OSCTUNE = 0


' ====== TEST PROGRAM ==============================================================================
TEST:
    TOGGLE PORTB.6
    pause 500
GOTO TEST
END

Unfortunately, the third example dosen't work either, this one:

' PIC 16F18426
#CONFIG
    __config _CONFIG1, _FEXTOSC_OFF & _RSTOSC_HFINT1 & _CLKOUTEN_OFF & _CSWEN_ON & _FCMEN_ON
    __config _CONFIG2, _MCLRE_ON & _PWRTS_PWRT_64 & _LPBOREN_OFF & _BOREN_SBOREN & _BORV_LO & _ZCDDIS_OFF & _PPS1WAY_OFF & _STVREN_ON
    __config _CONFIG3, _WDTCPS_WDTCPS_31 & _WDTE_SWDTEN & _WDTCWS_WDTCWS_7 & _WDTCCS_LFINTOSC
    __config _CONFIG4, _BBSIZE_BB512 & _BBEN_OFF & _SAFEN_OFF & _WRTAPP_OFF & _WRTB_OFF & _WRTC_OFF & _WRTD_OFF & _WRTSAF_OFF & _LVP_OFF
    __config _CONFIG5, _CP_OFF
#ENDCONFIG


' ====== DEFINES ===================================================================================
    DEFINE OSC 4
    ANSELC = $DF;
    OSCCON1 = $60; // CSWHOLD may proceed; SOSCPWR Low power;
    OSCCON3 = 0;  // MFOEN disabled; LFOEN disabled; ADOEN disabled; SOSCEN disabled; EXTOEN disabled; HFOEN disabled;
    OSCEN = 0 ;    // HFFRQ 4_MHz; 
    OSCFRQ = 2;  // HFTUN 0; 
    OSCTUNE = 0


' ====== TEST PROGRAM ==============================================================================
TEST:


    TOGGLE PORTC.5
    pause 500
    
GOTO TEST
END

Maybe this last code doesnt work because you seem to use a 16F8246 not a 16F18446 like I have.

Honestly, I can have a real good life with LATBs commands instead of TOGGLEs

[Ioannis]

TOGGLE will not work.

Richard did explain why at post #5.

So, you have to use either directly PORT or LAT commands. Personally, never liked the TOGGLE command and always preferred to use discrete commands. Bonus that you know the final state of the register. With TOGGLE you only know that it has changed. Not how.
