and press Enter on your keyboard. The assembly code at this
address appears in the Current Instruction field. It is the
addition of the variable bigcount with 2.

Type the assembler instruction ADD R10,#3 in the Enter New
Instruction field and press Enter. You could see the change of
your source code at address 0x64H.
•

4.6 Single Stepping
•
The debugger uses “Step Into” to single step one instruction at
a time. “Step Into” is also used to enter a function in the same
fashion.
•
“Step Over” means to skip over a function that you are
not interested in.
•
“Step Out” is used to exit a function you are currently in.
“Step Out” is very useful if you find yourself in a function you
are not interested in and need to return quickly to your intended
function.
•
If the debugger gets stuck, execute a reset using the RESET
icon located
next to the RUN icon. To isolate any
problems from the target hardware board you could use the
software simulator instead of the Monitor. You can also use the
hardware reset button on the board.
•
With the cursor on line 42 click on StepInto until you enter the
function stepout(). Note that you must click on StepInto 10
times to exit the for loop within the function stepout().
