[moved] Proteus bug 8.5SP0 - and pic 24fj16ga004

[Seegoon]

I can't get this simple program 10 lines of code to simulate correctly.
It works fine in mplab simulator. Using XC16 Ver 1.26.
Basically clearing the individual TRIS C registers and setting the appropriate latches.
At the end , doing it in 1 shot.

Is proteus really that useless?
Attached is "main.c" , Proteus project and .cof and .hex files , in a rar file

Below is the code , out of interest..

#include "xc.h"

_CONFIG1(JTAGEN_OFF & GCP_OFF & GWRP_OFF & BKBUG_OFF & ICS_PGx3 & FWDTEN_OFF & FWPSA_PR128 & WDTPS_PS256)
_CONFIG2(FNOSC_PRI & FCKSM_CSDCMD & OSCIOFNC_OFF & POSCMOD_HS)

int main(void)
{
    AD1PCFG = 0xFFFF;

    TRISCbits.TRISC0 = 0;
    LATCbits.LATC0 = 1;
    TRISCbits.TRISC1 = 0;
    LATCbits.LATC1 = 1;
    TRISCbits.TRISC2 = 0;
    LATCbits.LATC2 = 1;
    TRISCbits.TRISC3 = 0;
    LATCbits.LATC3 = 1;
    
    TRISC = 0;
    LATC = 0x02FF;
    while (1);

}

Forgot to add what Proteus does :0)
Instead of turning on latches C0 to C3 in turn Proteus does this.
START:
LATC0 =OFF
LATC1 =OFF
LATC2 =OFF
LATC3 =OFF

C0= ON
C1, C2 , C3 = OFF Correct to here :0)

C0 = OFF WRONG FROM HERE ON
C1 = ON
C2 , C3 =OFF

C0 =OFF WRONG
C1 = OFF
C2 = ON
C3 = OFF

C0 to C2 = OFF
C3 = ON

Cheers

What is the config value BKBUG? IF it is supposed to be DEBUG then *NEVER EVER* play with that setting - leave it to the IDE.

It's the default value BKBUG_OFF. This equates to 0x7FFF. Interestingly BKBUG_ON is also 0x7FFF , so it obviously makes no difference what you select.
