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
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.
