16.3
This section describes the memory map and registers for the Flash module. Read data from unimplemented
memory space in the Flash module is undefined. Write access to unimplemented or reserved memory space
in the Flash module will be ignored by the Flash module.
16.3.1
The S12 architecture places the P-Flash memory between global addresses 0x3_4000 and 0x3_FFFF as
shown in
The FPROT register, described in
accidental program or erase. Three separate memory regions, one growing upward from global address
0x3_8000 in the Flash memory (called the lower region), one growing downward from global address
0x3_FFFF in the Flash memory (called the higher region), and the remaining addresses in the Flash
memory, can be activated for protection. The Flash memory addresses covered by these protectable regions
are shown in the P-Flash memory map. The higher address region is mainly targeted to hold the boot loader
code since it covers the vector space. Default protection settings as well as security information that allows
the MCU to restrict access to the Flash module are stored in the Flash configuration field as described in
