Single wire interface module (SWIM) and debug module
The single wire interface module, SWIM, together with an integrated debug module, permits
non-intrusive, real-time in-circuit debugging and fast memory programming.
SWIM
Single wire interface for direct access to the debugging module and memory programming.
The interface can be activated in all device operation modes and supports hot-plugging. The
maximum data transmission speed is 145 bytes/ms.
Debug module
The non-intrusive debugging module features a performance close to a full-featured
emulator. Besides memory and peripheral operation, CPU operation can also be monitored
in real-time by means of shadow registers.

Writing, erasing, word and block register management is handled automatically by the
memory interface.
R/W of RAM and peripheral registers in real-time
R/W for all resources when the application is stopped
Breakpoints on all program-memory instructions (software breakpoints) except the
vector table
Two advanced breakpoints and 23 predefined configurations
