Security measure and control location
A security measure is a mechanism to either block or allow SAB access to a certain address or
address range. A security measure is enabled or disabled by one or several control signals. This
is called the control location for the security measure.
These security measures can be used to prevent an end user from reading out the code pro-
grammed in the flash, for instance.
Table 34-2.
Below follows a more in depth description of what locations are accessible when the security
measures are active.
Table 34-3.

Description
Programming and debugging not possible, very restricted
access.
Restricts all access except parts of the flash and the flash
controller for programming user code. Debugging is not
possible unless an OS running from the secure part of the
flash supports it.
