This command does not download the software. Use this command to access target regis-
ters, memory, and so on without loading new code or to avoid overwriting the target’s
code with the same code. This command is not enabled when the target is the simulator.
This command is available only when not in
Debug mode.
For the Serial Smart Cable, ZDS II performs an on-chip debugger reset and resets the CPU
at the vector reset location.
Download Code
The Download Code command downloads the executable file for the currently open proj-
ect to the target for debugging. The command also initializes the communication to the tar-
get hardware if it has not been done yet. Starting in version 4.10.0, the
Download Code
command can also program Flash memory. A page erase is done instead of a mass erase
for both internal and external Flash memory. Use this command anytime during a debug
session. This command is not enabled when the debug tool is the simulator.
The current code on the target is overwritten.
If ZDS II is not in Debug mode when the Download Code command is selected, the fol-
lowing process is executed:
1. Initializes the communication to the target hardware.
2. Resets the device with a hardware reset by driving pin #2 of the debug header low.
3. Configures the device using the settings in the Configure Target dialog box.
4. Downloads the program.
5. Issues a software reset through the debug header serial interface.
6. Configures and executes the debugger options selected in the Debugger tab of the
Options dialog box. If it is a C project, ZDS II resets to the main function if it is
found.

If ZDS II is already in Debug mode when the Download Code command is selected, the
following process is executed:
1. Resets the device using a software reset.
2. Downloads the program.
