There is a dedicated Flash bank for CPU subsystem. Also, there is a one-time programmable (OTP) memory called USER OTP, which the user can program only once and cannot erase. Flash and OTP are uniformly mapped in both program and data memory space.
The CPU subsystem has a TI-OTP that contains manufacturing information like settings used by the Flash state machine for erase and program operations, and so on. Users can read TI-OTP but TI-OTP cannot be programmed or erased. For memory maps and size information for the Flash Banks, TI-OTP, USER OTP, and corresponding ECC locations, refer to the device data sheet.
