Using SSE-200 MPU to modify specific region from normal to device memory

Hi,

The SSE-200 memory model (and the armV8m system address map) defines the 0x6000_0000-0x7FFF_FFFF as a "normal" memory region.

Using the SSE-200 MPU, we would like to configure this region as "device" memory with nGnRnE attributes to allow us to use it as AHB5 expansion port (for hooking up our own custom IP).

Looking at the arm V8M architecture reference manual, I dont see any issues/restrictions but just wondered if there is any reason why this cant be done?

Thank you

Sarah
