S12G Memory Map Controller (S12GMMCV1)
5.4.3
The S12GMMC is capable of mapping up 240K of flash, up to 4K of EEPROM and up to 11K of RAM
into the global memory map{statement}. Smaller devices of the S12G-family do not utilize all of the
available address space. Address ranges which are not associated with one of the on-chip memories fall
into two categories: Unimplemented addresses and reserved addresses.
Unimplemented addresses are not mapped to any of the on-chip memories. The S12GMMC is aware that
accesses to these address location have no destination and triggers a system reset (illegal address reset)
whenever they are attempted by the CPU. The BDM is not able to trigger illegal address resets.
Reserved addresses are associated with a memory block on the device, even though the memory block does
not contain the resources to fill the address space. The S12GMMC is not aware that the associated memory
does not physically exist. It does not trigger an illegal address reset when accesses to reserved locations
are attempted.
