This device includes up to five Flash banks. In addition, there is one-time programmable Flash memory (OTP) in each Flash bank. Flash and OTP are uniformly mapped in both program and data memory space.
There are two OTP regions. The first OTP region, TI-OTP, contains manufacturing information, trims, Flash operation settings, and other device data. TI-OTP can be read by the user application, but TI-OTP cannot be programmed or erased. The second OTP region, USER-OTP, is primarily used for programming device security (DCSM module) settings. USER-OTP can be programmed only once and cannot be erased afterwards. For information on the memory-map, Flash bank sizes, TI-OTP, USER-OTP, and corresponding ECC locations, refer to the device data sheet.
The Location of Zone-Select Block Based on Link-Pointer figure in the Dual Code Security Module (DCSM) chapter shows the user-programmable OTP locations in CPU1 USER-OTP. For more information on the functionality of these fields, refer to the ROM Code and Peripheral Booting chapter and the Dual Code Security Module (DCSM) chapter.
