Memory Modes
4-5
4.3.2 Processor Mode
The memory mode which executes externally located instructions while using the internal data RAM and I/O ports
is called processor mode. The internal instruction ROM and the internal flash memory are not used for this mode.
Processor mode has memory space of up to 3 GB from addresses x'00000000 to x'BFFFFFFF. Addresses x'00000000
to x'1FFFFFFF are the internal data space (up to 512 MB) which contains data, addresses x'20000000 to x'3FFFFFFF
are the internal I/O space (up to 512 MB) which is assigned to the I/O ports and control registers, and addresses
x'40000000 to x'BFFFFFFF are the external memory space (up to 2 GB).
This microcontroller has 8 Kbytes of data RAM located at x'00000000 to x'00001FFF.
Note that it is prohibited to access unmounted space of the internal data space and the internal I/O space. When
accessing the unmounted space, the operation is not assured.
