Debug Commands

µVision3 supports a number of commands you may enter in the Output Window — Command Line. Commands may be separated into categories that describe the common function of the commands.

The commands can be grouped into the following categories:

Breakpoint Commands

Breakpoint commands let you create and delete breakpoints. You use breakpoints to halt program execution or to execute µVision3 commands or user functions when a particular instruction is reached.

Command	Description
BreakAccess	Add an access breakpoint with length to the list of breakpoints.
BreakDisable	Disables one or more breakpoints.
BreakEnable	Enables one or more breakpoints.
BreakKill	Removes one or more breakpoints from the breakpoint list.
BreakList	Lists the current breakpoints.
BreakSet	Adds a breakpoint expression to the list of breakpoints.

General Commands

General commands let you perform a number of miscellaneous debugging operations.

Command	Description
ASSIGN	Assigns input and output sources for the Serial window.
DEFINE	Creates a Toolbox button.
DIR	Generates a directory of symbol names.
EXIT	Exits µVision3 debug mode.
INCLUDE	Reads and executes the commands in a command file.
KILL	Deletes µVision3 debug functions and Toolbox buttons.
LOAD	Loads object modules, and HEX files.
LOG	Creates log files, queries log status, and closes log files for the Debug window.
MODE	Sets the baud rate, parity, and number of stop bits for PC COM ports.
RESET	Resets µVision3, resets memory map assignments, and resets predefined variables.
SAVE	Saves a memory range in an Intel HEX386 file.
SCOPE	Displays address assignments of modules and functions of a target program.
SET	Sets the string value for predefined variable.
SIGNAL	Displays signal function status and removes active signal functions.
SLOG	Creates log files, queries log status, and closes log files for the Serial window.

Memory Commands

Memory commands let you display and change the contents of memory.

Command	Description
ASM	Assembles in-line code.
DEFINE	Defines typed symbols that you may use with µVision3 functions.
DISPLAY	Display the contents of memory.
ENTER	Enters values into a specified memory area.
EVALuate	Evaluates an expression and outputs the results.
MAP	Specifies access parameters for memory areas.
Unassemble	Disassembles program memory.
WatchSet	Adds a watch variable to the Watch window.
WatchKill	Kill all watch variable in the Watch window.

Program Commands

Program commands let you execute your target program and analyze its performance.

Command	Description
COVERAGE	Display code coverage information.
Go	Starts program execution.
LogicAnalyze	Initializes the Logic Analyser.
PerformanceAnalyze	Initializes the built-in performance analyzer.
Pstep	Steps over instructions but does not step into procedures or functions.
Ostep	Steps out of the current function.
Tstep	Steps over instructions and into functions.

Command Entry

During command entry, the syntax generator displays possible commands, options and parameters. As you enter commands µVision3 reduces the list of likely commands to coincide with the characters you type.

If you type B, the syntax generator reduces the commands listed.
Available command options are listed if the command is clear.
The syntax generator leads you through the command entry and helps you to avoid errors.
