• A User Triggers mode, which provides two complex breakpoints, triggers A and B,
one complex watchpoint, trigger C, and two spares classic hardware breakpoints that
can bet as usual (not in the dialog).
• A Profile and Coverage mode, which provides code profiling and coverage
information when opening the Profiler and Coverage components. Note that these
features are not real time. The debugger can only access the DBG on-chip trace
buffer/FIFO when the device is halted. Therefore, in background, the debugger
regularly halts the device, retrieves debug information, then restarts the device, to
build a statistic program counter database. Refer to
Profiling and Coverage Mode .

Automatic Mode
Automatic provides only two behaviors for the Trace window in the Trace Settings list
menu:
• Disabled: not recording any data and not displaying anything in the Trace window,
• Enabled: recording continuously. Each time the debugger is halted, the Trace
window is refreshed with the latest program flow recorded.
