Trace Setup dialog box

In this section:

Use this dialog box to configure trace generation and collection. Some of these settings are also used by the interrupt logging.

The C-SPY E1/E2/E20 driver. Note that trace requires that interrupt logging is disabled.

Enables trace data collection.

Empties the trace buffer before each Go or step command is performed.

Controls what C-SPY does when the trace buffer is full. Choose between:

Overwrite oldest frames: The oldest frames are overwritten until a break occurs. If trace is disabled and interrupt logging is enabled, this setting means that the Interrupt Log window will display the last log entries before the break (~500 entries).
Stop tracing: The trace stops when the trace buffer is full.
Break execution: The trace stops and execution breaks when the trace buffer is full. If trace is disabled and interrupt logging is enabled, the Interrupt Log window will display all log entries in the buffer (~500 entries).

Controls how the trace collection is performed. Choose between:

Realtime: Trace is performed at full execution speed. At this speed, some trace data will not be collected, leading to gaps in the information displayed in the Trace window.
Non realtime (Full trace): A full trace is performed. The trace collection starts at any Go or step command, and stops at break.

Determines which types of trace data that C-SPY collects. Choose between:

Branch PC + Data access: Collects both the contents of the program counter on branches, and data access information.
Branch PC: Collects the contents of the program counter on branches that occurred during program execution.
Data access: Collects data access information.

Restores the default settings.
