3.5
Each memory can be implemented in its maximum allowed size. But some devices have been defined for
smaller sizes, which means less implemented pages. All non implemented pages are called unimplemented
areas.
3.5.0.1
The global memory spaces reserved for the internal resources (RAM, D-Flash, and P-Flash) are not
determined by the MMC module. Size of the individual internal resources are however fixed in the design
of the device cannot be changed by the user. Please refer to the SoC Guide for further details.
and
spaces have fixed top addresses.
In single-chip modes accesses by the CPU12 (except for firmware commands) to any of the
unimplemented areas (see
to the unimplemented areas are allowed but the data will be undefined.
No misaligned word access from the BDM module will occur; these accesses are blocked in the BDM
module (Refer to BDM Block Guide).
