Hello,guys.

write this code:

init_data    idata
        db 0x12
        db 0x13, 0x14, 0x15

    code
        movf (init_data + 2), W

    end



this can not work, the data of init_data is in flash, I have look up the
HEX file,there is no code get the data from flash to ram before the value
is used( movf (init_data + 2), W ).

Why there is no code..??

thanks.
