Chapter 30 Security (S12X9SECV2)
30.1.2
30.1.3
Once the user has programmed the Flash and EEPROM, the chip can be secured by programming the
security bits located in the options/security byte in the Flash memory array. These non-volatile bits will
keep the device secured through reset and power-down.
The options/security byte is located at address 0xFF0F (= global address 0x7F_FF0F) in the Flash memory
array. This byte can be erased and programmed like any other Flash location. Two bits of this byte are used
for security (SEC[1:0]). On devices which have a memory page window, the Flash options/security byte
is also available at address 0xBF0F by selecting page 0x3F with the PPAGE register. The contents of this
byte are copied into the Flash security register (FSEC) during a reset sequence.

EEPROM Array Access
Availability of Flash arrays in the memory map depends on ROMCTL/EROMCTL pins and/or the state of
the ROMON/EROMON bits in the MMCCTL1 register. Please refer to the S12X_MMC block guide for
detailed information.
Restricted NVM command set only. Please refer to the FTX/EETX block guides for detailed information.
BDM hardware commands restricted to peripheral registers only.
