That is from my point of few not the job of ddd. If you have a simple 
struct defined with all the IO registers of the device you could display 
them simply by watching the struct content. There is really no 
difference in IO registers and any other memory structure. But sometimes 
watching IO regisers change the value, like reading uart data input 
registers will remove data from the peripheral which is also done if you 
watch on some targets through jtag into the device. Some registers 
should be hidden in this case. Any idea how this could performed with 
actual ddd? Lauterbach Trace 32 is very good in this case. Maybe we 
could add some functionality from this.
