13.3
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.
13.3.1
The S12 architecture places the P-Flash memory between global addresses
shown in Table
The FPROT register, described in
accidental program or erase.
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.
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
Table

1. 0x3FF08-0x3_FF0F form a Flash phrase and must be programmed in a single command write sequence. Each byte in
0x3_FF08-0x3_FF0B
the 0x3_FF08 - 0x3_FF0B reserved field should be programmed to 0xFF.
