Disabled Mode
The user needs to know the on-chip DBG module to use this mode. It can be seen as a “Do
It Yourself” way to set hardware breakpoints, watchpoints, and triggers. Consult the
Reference Document section and documents to get all information about the HCS08 on-
chip DBG module before attempting to use this mode.
There is no dedicated graphical user interface to access the DBG module register. The
triggers comparator addresses and DBG control registers are handled by the user through
the debugger Memory component or using command line commands. The DBG module is
NOT set by the debugger. DBG module enabling and arming depend on the selected flags
set within the DBG register control registers. The DBG module is NOT reset when the
application stops. By default, the FIFO content is protected from unexpected reads, the
DBG module is automatically disarmed and the FIFO is analyzed when the debugger
stops. This can be optionally disabled by the user.
