Chapter 10 Code Protection and Security

10.1 Overview

The microcontroller supports various methods for protecting the program code 
in the flash memory from undesired access, such as illegal read-out or illegal 
reprogramming.

Some interfaces offer in general access to the internal flash memory: N-Wire 
debug interface, external flash programmer interface, self-programming 
facilities and test interfaces.

In the following the security relevant items are listed. The features to protect 
the internal flash memory data from being read by unauthorized persons are 
described.

For more information on the flash memory, see 

“Flash Memory“ on page 229

.

The following sections give an overview about supported code protection 
methods.

10.2 Boot ROM

Undesired access to the flash memory via the boot ROM is not possible.

10.3 N-Wire Debug Interface

In general, illegal read-out of the flash memory contents is possible via the 
N-Wire debug interface. For protection of the flash memory, the usage of the 
debug interface can be protected and it can be disabled. The debug interface is 
protected via a 10-byte ID code and an internal flag (N-Wire use enable flag). 

When the debugger is started, the status of a flag is queried (N-Wire use 
enable flag). Set this flag to zero to disable the use of the N-Wire in-circuit 
emulator. 

When debugging is enabled (N-Wire use enable flag is set), you have to enter 
a 10-byte ID code via the debugger. The code is compared with the ID code 
stored in the internal flash memory. If the codes do not match, debugging is not 
possible. 

The N-Wire use enable flag can be set or reset while reprogramming the flash 
by an external flash writer or with the self-programming feature. The flag is 
located at bit 7 at address 0000 0079

H

.

You can specify your own 10-byte ID code and program it to the internal flash 
memory by an external flash writer or with the self-programming feature. The 
ID code is located in the address range 0000 0070

H

 to 0000 0079

H

. 

The protection levels are summarized in
