3.4.2.3
The global memory spaces reserved for the internal resources (RAM, EEE, and 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 Device User Guide for further details.
Figure 3-19
the memory spaces have fixed top addresses.
When the device is operating in expanded modes except emulation single-chip mode, accesses to global
addresses which are not occupied by the on-chip resources (unimplemented areas or external memory
space) result in accesses to the external bus (see
