NEC devices offer a state of the art protection of the flash contents against a fraudulent read-out of the flash contents. This protection is achieved by implementing a whole range of features.

There are different channels to access the flash which need to be considered independently:

??Flash programming Interface, or the so called �Serial Programming Mode?
??Debugging Interface
??Self-programming mode
??Normal operation mode with instruction and data fetch from the flash

The protection of each of those access types is described independently as those protection features are quite independent of each other.
