S12X Debug (S12XDBGV3) Module
6.1
The S12XDBG module provides an on-chip trace buffer with flexible triggering capability to allow non-
intrusive debug of application software. The S12XDBG module is optimized for the S12X 16-bit
architecture and allows debugging of CPU12X module operations.
Typically the S12XDBG module is used in conjunction with the S12XBDM module, whereby the user
configures the S12XDBG module for a debugging session over the BDM interface. Once configured the
S12XDBG module is armed and the device leaves BDM Mode returning control to the user program,
which is then monitored by the S12XDBG module. Alternatively the S12XDBG module can be configured
over a serial interface using SWI routines.
