Single wire interface module (SWIM) and debug module (DM)
The single wire interface module and debug module and permit non-intrusive, real-time in-
circuit debugging and fast memory programming.
SWIM
Single wire interface module for direct access to the debug module and memory
programming. The interface can be activated in all device operation modes. 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. Beside memory and peripherals, also CPU operation can be monitored in real-
time by means of shadow registers.
