240 KByte Flash Module (S12FTMRG240K2V1)
The FPROT register, described in
accidental program or erase. 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
Table

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