PostPosted: Thu Apr 25, 2019 8:34 am     Reply with quote

Again, the device is a PIC24FJ1024GB610 and I'm trying to port PIC18F code to PIC24FJ device.

On PIC18F I was using the following code to clear the GPRs (Non SFR RAM)

Code:

void CleanRAM()
{
        #asm
        movlw   0x0F
        movwf   FSR0H
        movlw   0x3F
        movwf   FSR0L
NextByte:               
        clrf    POSTDEC0
        tstfsz  FSR0H
        bra     NextByte
        tstfsz  FSR0L
        bra     NextByte
        clrf    INDF0
        #endasm
}



I was think in to use pointers but CCS will put that pointer in the same memory that I'm trying to erase(set to zero) so this ain't going to end well.

Any suggestion about how to get this goal?
