An initialization file consists of text instructions telling the debugger how to initialize
the hardware after reset, but before downloading code. You can use initialization file
commands to assign values to registers and memory locations, and to set up flash
memory parameters.
The initialization files of your IDE are on the path:
{CodeWarrior path}\M56800E Support\initialization
The name of each initialization file includes the number of the corresponding
processor, such as 568345. Each file with “_ext” enables the processor’s external
memory. If the processor has Flash memory, the initialization file with “_flash”
enables both Flash and external memory.
To set up an initialization file:
Table 4.13 Debugging M56800E Target Panel Elements
Element Purpose Comments
Always reset on
download
checkbox
Checked — IDE issues a reset to the target
board each time you connect to the board.
Clear — IDE does not issue a reset each
time you connect to the target board.
Use initialization
file checkbox
Checked — After a reset, the IDE uses an
optional hardware initialization file before
downloading code.
Clear — IDE does not use a hardware
initialization file.
The Use initialization file text box
specifies the file.
Text immediately after this table gives
more information about initialization
files.
Use initialization
file text box
Specifies the initialization file. Applicable only if the Use initialization
file checkbox is checked.
Breakpoint Mode
checkbox
Specifies the breakpoint mode:
• Automatic — CodeWarrior
software determines when to use
software or hardware breakpoints.
• Software — CodeWarrior software
always uses software breakpoints.
• Hardware — CodeWarrior software
always uses the available
hardware breakpoints.
Software breakpoints contain debug
instructions that the debugger writes
into your code. You cannot set such
breakpoints in flash, as it is read-only.
Hardware breakpoints use the on-
chip debugging capabilities of the
DSP56800E. The number of
available hardware breakpoints limits
these capabilities.
Note, Breakpoint Mode only effects
HW targets.
Auto-clear

Checked — Automatically clears the
previous harware breakpoint.
Clear — Does not Automatically clears the
