The fixed 16KB page from 0x0000 to 0x3FFF is the page number 0x0C. Parts of this page are covered by
Registers, D-Flash and RAM space. See SoC Guide for details.
The fixed 16KB page from 0x4000–0x7FFF is the page number 0x0D.
The reset value of 0x0E ensures that there is linear Flash space available between addresses 0x0000 and
0xFFFF out of reset.
The fixed 16KB page from 0xC000-0xFFFF is the page number 0x0F.
3.4
The S12PMMC block performs several basic functions of the S12P sub-system operation: MCU operation
modes, priority control, address mapping, select signal generation and access limitations for the system.
Each aspect is described in the following subsections.
3.4.1
3.4.2
3.4.2.1
The BDM firmware lookup tables and BDM register memory locations share addresses with other
modules; however they are not visible in the memory map during user’s code execution. The BDM
memory resources are enabled only during the READ_BD and WRITE_BD access cycles to distinguish
between accesses to the BDM memory area and accesses to the other modules. (Refer to BDM Block
Guide for further details).
When the MCU enters active BDM mode, the BDM firmware lookup tables and the BDM registers
become visible in the local memory map in the range 0xFF00-0xFFFF (global address 0x3_FF00 -
0x3_FFFF) and the CPU begins execution of firmware commands or the BDM begins execution of
hardware commands. The resources which share memory space with the BDM module will not be visible
in the memory map during active BDM mode.

Normal single chip mode
This is the operation mode for running application codeThere is no external bus in this mode.
Special single chip mode
This mode is generally used for debugging operation, boot-strapping or security related
operations. The active background debug mode is in control of the CPU code execution and the
BDM firmware is waiting for serial commands sent through the BKGD pin.
