S12S Debug Module (S12SDBGV2)
6.1
The S12SDBG module provides an on-chip trace buffer with flexible triggering capability to allow
non-intrusive debug of application software. The S12SDBG module is optimized for S12SCPU
debugging.
Typically the S12SDBG module is used in conjunction with the S12SBDM module, whereby the user
configures the S12SDBG module for a debugging session over the BDM interface. Once configured the
S12SDBG module is armed and the device leaves BDM returning control to the user program, which is
then monitored by the S12SDBG module. Alternatively the S12SDBG module can be configured over a
serial interface using SWI routines.
