HCS08 On-Chip DBG Module
Trace Component Window
533 Microcontrollers Debugger Manual
It is not necessary to open the Trace window/component to make use of the DBG user
interface triggers. However, several triggers are used to collect code program flow
information or access data information. The Trace window can be opened from
Specific
Connection Menu Options , from Context Menu Entries in Source, Data, Assembly and
Memory Windows , and from the DBG Support Status Bar Item . The window can by saved
in the debugger layout when pressing the debugger Save icon.
NOTE When the Trace component/window is closed, the debugger might be faster, as
code program flow rebuild is discarded, this last disassembling back the
assembly data from the connection CPU’s memory.
Instructions Display
This display mode is automatically set when Instruction Triggers and Memory Access
Triggers are used. It is also the default display in Automatic Mode (Default) .
Displayed columns:
• Frame: A number representing an information item stored in the Trace component
database.
• Address: instruction program counter.
• Instruction: code program flow instruction disassembly.
• FIFO Analyze remark: debugger information: DBG FIFO data means that this data
was recorded by the on-chip DBG module. Traced means an item/instruction
obtained by debugger/user single step or assembly step. Program flow rebuild gap
means that the debugger was unable to completely track the code program flow
between two frames.
