Implemented Memory Map
The global memory spaces reserved for the internal resources (RAM, EEPROM, 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 17-23 and Table 17-20 show the memory spaces occupied by the on-chip resources. Please note that
the memory spaces have fixed top addresses.
