    I'd like to know what changes i have to do in the START167.A66 to use 64k of external multiplexed 16 adresses/8 data memory with the st10f168.
    It's the first time I use the Keil tools and I'm a bit lost.


    Thanks

    Hi this is really not important,
    since the startup is very good explained by commends.
    Take a copy in your project folder - open the
    startup file and look for example at

    $SET (BUSCON1 = 0)
    There you will find , that you have to set to 1 to initialize the BUSCON1 register.
    At this section you find e.g.
    _BTYP1 EQU 2 what you have to set to
    _BTYP1 EQU 3
     for 16 bit multiplexed bus.
    Do so for all settings.
    May be it takes a while the first time but you can nearly exact match all your needs here.
    Hope this helps, since I can not explain here all settings of the startup. Stefan
