VersaKit-30xx

Once a breakpoint is reached, you can either:

•

Restart the program by clicking again on run .

•

Single step through the code by clicking on step .

•

View/Edit the SFR, IRAM, XRAM memory location by clicking SFR

, IRAM

and XRAM

buttons.

When step

is clicked, the processor will execute the current instruction and step to the next instruction (and actually

stop). The SFR, IRAM, XRAM or FRAM memory content can be viewed and edited at any time after a breakpoint is

reached (this includes step

mode). The debugger provides table and list view options for the SFR, IRAM, XRAM and

FRAM memory areas. It is also possible to open multiple windows for each of these memory areas.

Editing a given SFR, IRAM, XRAM and FRAM memory cell is simple:

•

Double click on the memory location to be edited.

•

Type in the new value to be written.

•

Press <Enter> or double click another memory location.

Notes on the SFR edition:

In the case of the SFR memory location, it is important to note that some registers are partially or totally read or write only

or can only be accessed when the related peripheral is activated. The SFR edition feature allows the user to partially

control the peripheral.

5.5 Updating the Code without exiting the debugger

If during a debug session, you want to modify the code, recompile and reload the code into the Flash memory. The Versa

Ware JTAG allows you to reload the code in Flash memory without exiting the Versa Ware JTAG debugging environment.

To do this, open the editor, modify the code and recompile it. Then return to the debugger and click on erase then

program

button. Note that all the breakpoints you have set will be lost.

5.6 Exiting the Debugger

To exit the debugger, click on stop debugging . This will bring you back in the Versa Ware JTAG programming

environment.
