8.3.1 User OTP

User OTP space is available for permanent storage of application specific data. User OTP Flash programming, data read and CRC access is permitted in all modes. Execution from User OTP Flash is not permitted. User OTP space is not erased on a chip erase. User OTP Flash words should only be programmed once. This must be enforced by firmware; there is no hardware access control that prohibits programming a Flash word multiple times. The User OTP space is separate from the Flash protection region OTP capability.
