ST10F168 : Internal/External address bus

Joffrey Kriegel

Hello,

I'm currently working on the ST10F168 and I'm using the external bus to control some RAMs.

But when I don't use the external RAMs, the external address bus is still changing.

So I would like to know if it's normal, and if it is the same bus which is connected to the external RAMs and to the internal RAM.

If it's the case : if I make an access to an internal address, can the address be seen on the external bus too ?

Thanks.
