Using the Command Line to Change Register Values
To use the Command line to change the value contained in a register:
1. Select Window > Command to view the Command window (Figure 5.3). If you do
not see the Command window:
a. From the debugger main menu select Component > Open
b. Select Command
c. Click OK — the debugger opens a new Command window.
Figure 5.3 Command Window in the Debugger
2. Click on command line (place insertion point on command line)
3. Type RS — the Command window displays the syntax of the RS command
4. Use the RS command to set register values — for example. to set the value of the
program counter (PC) to hexadecimal 1ECB , type:
RS PC = 0x1ECB
You can also use the RD command in the Command window. The RD command
displays the current values contained in the registers. For more information on the RD
and RS commands, see the documentation that accompanies the CodeWarrior
software.
Viewing Memory
The Memory window displays the values stored in the target memory. It displays RAM
and ROM values updating in real-time during code execution if you select the periodic
dispay mode. You can view the values in different numeric formats, such as decimal,
hexadecimal, and binary.
To view values stored in target memory:
1. From debugger main menu, select Window > Memory to view the Memory window
(Figure 5.4). If you do not see the Memory window:
a. From the debugger main menu select Component > Open
b. Select Memory
